Ondrej's place is great! The location is perfect and in the heart of Prague. You can walk to everything. We had 3 people on the trip. It was cozy, but if you're out all day sightseeing and using it for breaks/sleep/morning prep, then it's perfect. It's across the street from a couple bars so can get a little noisy, but no different than being in an apartment in a big US city, which we are used to. Would definitely recommend staying here!
