My husband and I were booked in here for 5 nights recently by his company for his business trip - me just along to visit Amsterdam for the first time. It was a convenient choice for us both.
The easiest way to arrive from the airport is to take the train (tickets on sale in the airport luggage hall) and walk onto the platform five minutes away. We were in Central Station in 15 mins. Walk just outside and get on a no 4 or 9 tram (it's the terminus, so no worries about which direction to go!). Ask for the Rembrandtplein (square), about 5 mins away, and the hotel is immediately opposite. So, much cheaper - and quicker - than a taxi or the hotel shuttle bus, for which there were huge queues.
The hotel is supposed to be an Amsterdam 'landmark' - over 100 years old. I was initially disappointed; the entrance and lobby are small and dark and looked a little worn. The lift is antiquated.
But the staff couldnt have been more helpful. Having read Tripadvisor reviews I had asked for a quiet room at the rear,and this was the best piece of advice I got!! The noise at the front of the hotel must be awful at night and especially at weekends with all the bars and cafes in the square and the clanking trams!
Butwe were upgraded to a more spacious business room at the rear which was comfortable and very quiet. The beds were extremely comfortable, bathroom small but perfectly adequate with masses of hot water; nice flatscreen TV
Breakfasts in the Cafe Schiller were good - a range of hot and cold dishes, plenty of fruit, choice of lovely breads etc. You could even have sparking champagne if you wanted! And the cafe area was what actually 'grew on me'; it was quite nice to be in an older
building with some character and charm instead of the usual modern hotel areas you find everywhere.
The best thing was the convenience of being able to walk to every major sight in minutes. Turn left out of the hotel and left again and within two minutes you were on the quietest canals with their wonderful architecture. Two minutes in the other direction and you were in the heart of the city.
We ate in some good restaurants - but the best by far was again two minutes away - down the road to the left of the hotel which leads to the canal. On the corner over the first bridge is a tiny Italian place - only about 8 tables - called Ponte Arcelo (or something like that!) run by two Italians. Fantastic food - whatever was fresh that day - you had to pay cash, but it was so cheap and absolutely delicious - a real find.
So, overall a good stay - but remember to get that room at the back of the hotel if you plan any sleep at all!

I had been warned to go for as high standard of hotel as possible in Amsterdam, I got a good deal on the Schiller which included breakfast, but I could honestly say I wouldnt class this as a 4 star hotel. It was a very nice hotel, the beds were extremely comfortable, we had a lovely (small) room overlooking Rembrandt square, the room had a balcony which was really nice (although you wouldn't spend too much time out on it in feb..brrrr), I would like to see that during the Summer! The noise wasn't as bad as I expected from the square, but definitely if you were a light sleeper I'd say it would be a different story! The toiletries in the bathroom definitely deserve a mention, they were lovely, I smelled like a fruit salad for the weekend!!!
I found the staff to be very friendly and helpful, both on reception and in the bar -drink prices are quite saucy in the bar though..you have been warned!! - the lady who served us breakfast was particularly nice. The breakfast was delicious, with a great selection of pretty much everything, and kept well topped up.
There was some kind of party on downstairs on the Saturday night, and the music was VERY loud, it didnt bother us too much as we were heading out ourselves, but if you were planning an early night it would have been fairly upsetting! (although who would have an early night on Saturday in Amsterdam??)
All in all I would return to the NH Schiller because I have no real negatives about my stay, but I would be looking for a special offer again, as I wouldnt pay 4 star prices for it.

Great hotel in a central location of Amsterdam. The tram drops you off just across the street, it could not have been any more convenient. The staff were friendly and helpful. The rooms were well appointed and we got a great rate when we booked in advance. You are in walking distance of many of the city's attractions. We'd definitely stay again next time we visit Amsterdam.

The hotel location and confort are good.
The restaurant was very good and its staff absolutely amazing.

Unfortunately, the hotel staff were not very pleasant, or helpful.
There was a private party going on on the Saturday night till past midnight, with live music etc...We would have appreciated if someone had told us at the time of check in. The music was very loud and even on the 6th floor we couldn't hear ourselves thinking.

The room only contained 1 glass and 1 mug, I asked twice to get second ones, I am still waiting.

All in all a good experience but could have been wonderful if the staff in the hotel was as good as in the restaurant.
