I enjoyed my stay at Roman’s flat. The bed was comfortable and being surrounded by books was a nice touch! The shower was hot and bathroom was adequate — though the ceiling was a bit low near the sink, I am tall so had to watch my head. You must walk up flights of stairs to access the flat. It was no problem for me, just an FYI. It is a bit of a walk to the center of things (about 25 minutes) though training is also an option. Overall, I enjoyed my stay and felt Roman was a communicative, nice host (though I never met him in person). In Prague I recommend the Jewish Museum (in an old Synagogue) and doing a walking tour to learn the history. It is a very historical and uniquely beautiful city!
