We had a wonderful stay! While it may not be the most stylish apartment in the world, it certainly is everything you could need for a short trip. We loved the area the apartment is in, very walkable to the inner city (we didn't take transportation once while we were there, except to get to/from the airport), yet far enough away that you don't feel like you're in a tourist trap. It's also a very quiet area (although we were there early in the week), which is nice. The bar directly below the apartment is absolutely adorable, but even when the bar was busy we did not hear a peep from the apartment! My only complaint was that it was pretty cold in the apartment even though we had the heat all the way up. That really didn't bother us much though since the only time we were in the apartment was to sleep, and there were plenty of blankets.
Lenka and Jaroslav were extremely responsive and we did not have any trouble getting into the apartment. Overall a great trip!
