Martin's apartment is right in the heart of the city. The location couldn't get much better than this. You walk out the main door of the building and you are in Old Town Square and there is always activity! Now you might think it would be noisy, but the apartment is amazingly quiet, likely due to the double-windows (and I mean actual double as in two windows per window, not just double-pane). We slept fine every night and nothing woke us up. As for the comments about the stairs in some reviews, it's only a minor hassle if you are bringing a lot of luggage when you arrive, but it really isn't a big deal. If for some reason you are allergic to stairs then maybe look somewhere else, but my wife and I didn't have a problem with them at all. The location is worth the little bit of exercise :) One tip I have for future guests: however you arrive at the square (taxi/rental car) try to drop your luggage off on "U Radnice" street near Hotel Rott and the Hard Rock Cafe. It is the shortest distance to the apartment from the street, so you don't end up dragging all your luggage across the complete square like I did (Old Town Square is a very large public square). Have fun!
