Maria's apartment is amazing! Cozy rooms, nice balkony and a beautiful view!!! We enjoyed it a lot. Although it was a bit shocking when we had to go up from the metro station with our baggage, and still carry it up to to 5th floor. In that moment I realized why she suggested to use the taxi :) then it is only the stairs you have to climb...
The location is also very good, most of the sights you can reach even by walk.
