We enjoyed our stay with Marina, as she is a most hospitable and supportive host.
The bedroom is clean and neat, and the private bathroom (only for us to use) was pleasant and comfortable.
As numerous other posts have noted, it was good to have restaurants, cafes, supermarket and Metro all within ~5 min. walk of the apartment.
Thank you Marina, for your warmth and goodwill-the A3 city map and discussions about what to do and where to go, together with 'language smoothing' with Google Translate(!), were especially helpful!
