This place was really wonderful. The elevator does take you to the top floor, but then you do have a very brief walk up a spiral staircase.
The location could not be better from the view point of quality restaurants, points of interest, super market, etc. Most everything, save the Prague Castle, is an easy walk! The apartment is quite large with two full bedrooms (one master with BOTH shower and bath) and two full baths. The bedrooms are reminiscent of Paris' chambre de bonne with their sloping ceilings and skylight windows. The kitchen is nicely equipped (pots, pans, cutlery, dishes, spices, olive oil and balsamic vinegar, etc) and functional! And the view from the living room is rather impressive.
If you are visiting for more than a couple of days, as we were, the large projector TV comes with a DVR loaded with a number of movies. There is a little something for everyone! We initially had some issues with the projector but Rob was nearby and helped us out. Unfortunately, if you're from the US, don't count on using Netfix (the is an app loaded). But as of this writing, Boxee (the system used), won't allow that. Also, general "TV" isn't available. But you do have movies!
After two weeks of travel, the clothes washer/dryer was very much appreciated and very easy to use!
Lastly, because you're in the heart of the city, weekend street noise is a bit louder in the bedrooms (they are street side). And, although the bedroom windows do have pull down blinds but they are not blackout, so the rooms give off a fair amount of light. We used eyemasks and ear plugs and had no problems.
