We had a great stay at Gabriela and Michal’s place. It’s just as described, spacious and open. Very quiet and clean, in a great older building. On the 5th floor but with a small elevator. When we had a question about the how to use the heating system, the hosts responded quickly with helpful advice and even offered to bring over a supplemental heater, although we didn’t end up needing it. Having the bedroom upstairs is a bit inconvenient but if you don’t mind the stairs it’s actually kind of quaint. It’s not far to the nearest metro station but Prague is such a walkable city we didn’t even use it. All in all we had a very nice experience and recommend it if you’re looking for an apartment for 2 in Prague.
