I stayed in May 2014 with some friends and this time I returned with my wife.
We booked an Executive Queen with Balcony. The room was on the 10th floor and we had a good, but not uninterrupted, view of the City. Our balcony was more of an elongated roof patio and was very nice.
Simply due to the timing of our flight and a train in to the City we arrived spot on 3:00 which is the very strict check-in time. Had we arrived earlier and tried to check in there is an "early check-in fee" of a very hefty E40. However, our room was not ready at 3:00. We were given a voucher for 2 beers in the Sky Lounge. All well and good but we wanted to have a wash and brush-up and to get out in to the City. How about offering this E40 "fine" in reverse and if your room is not ready then they give you E40 from your bill. Would this not be better customer service. I do not know of any other hotel that will charge you if you arrive to find your room is ready but it is not 3:00 so you must pay a lot of money.
This gripe aside we found the hotel to be lovely. Very clean, very comfortable and extremely centrally located. All of the staff we encountered did seem genuinely pleased to be serving us.
The Executive Lounge is not a great size and it got too crammed when they were handing out the free booze that we decided not to bother. Also, if you arrive for breakfast at a busy time it is like feeding time at the zoo and this is when you find that people forget their manners and push in front of you or become very greedy and take way too much stuff. The Executive breakfast only has scrambled egg as a hot option, the non-executive breakfast did have a vast array of hot dishes but paying punters have to pay E25 for this option and it is not available to those of us with "executive" privileges.
As we were on the 10th floor we were directly below the Sky Lounge and I was woken at 0100 on the Saturday night by the thump of music, presumable from the lounge. Perhaps management may wish to consider that not everyone in their hotel likes loud music and partying until the early morning. Some people actually rent bedrooms (a hotel's basic trade) to sleep. Why does the music have to be so loud?
This said, if we are in Amsterdam again we will stay here again. It's a nice place to be, it's not cheap but you get what you pay for. If I could give 3.5 stars I would do so as it I somewhere between "average" and "very good".
