Spent just one night here on a trip to Amsterdam for a concert at the Concertgebouw. The welcome was friendly and helpful - we got useful advice about tram and gallery tickets. Our room was, of course, quite small (this is Amsterdam) but roomy enough for two, and with a fine bathroom - including whirlpool bath. There is free wi-fi, but I forgot to ask for the password. Our double bed actually was a double bed - not two singles pushed together.
The breakfast buffet was excellent - containing all the usual ingredients, and it was a delight to sit at the window and watch the bike commuters flocking by on their way to work.
The location is fine. There is a tram stop about 50 meters from the hotel, with trams into the centre every few minutes.
All in all, an ideal hotel for a short stay. We will certainly be back.
