Okay! -- If you're like me, and you only skim-read the description, there are two things you must know about this place.
First, you might have to go to a bookshop to pick up the keys. The bookshop is a 40-minute walk away, or a 20-minute tram ride and a walk away. The walk is a world-class walk full of memorable views of Prague -- but still. Be aware. If you're fresh off of an international flight and new to Prague and dragging your luggage, that's going to feel like a lot.
Second, the apartment is up three flights of stairs. Not a big deal, but, for some people (my mother-in-law, for instance), that would be insurmountable. For others, it's just a short workout.
This is a lovely apartment with a great central European vibe, particularly if you're a reader. It's a corner apartment on the third floor, and, out the window, you can see the nearby monastery (which is particularly beautiful at night). For a certain kind of person, it's probably everything you want in a stopover in Prague: quiet, charming, cozy, and local.
The neighborhood is fantastic. I say this because it is also my neighborhood. (We rented this place while our flat was being painted.) It's close enough to get into and out of the historical parts of Prague, but far enough away that you can retreat a bit. It's also very close to Vysehrad, a park on the remains of an old castle, and one of my favorite places in the whole world. If you take the apartment, delight yourself, and go up there at your first opportunity. There are a number of places to get a coffee or a beer; there's a fascinating cemetery; there are views that you will love. We usually take our friends up there on their first night here to get them oriented and to show off a bit.
On the whole, we loved this place and would be happy to stay here again or refer friends to it.
