Robert's place is very close to the center of Old Town and a short walk from the Astronomical Clock (my favorite part of Prague). He was very accommodating. Fair warning: there are three flights of stairs and no lift so it was hard to carry up luggage and carry-ons up all those stairs. Also, there is very little privacy for the shower so it was a little odd trying to shower with my mom staying with me but we found ways to manage. Other than those two things, the stay was great. Would definitely recommend.
