We loved our stay at Natalia's apartment. She was very helpful when we arrived, meeting us at a later time than we had originally agreed upon, and was also quite helpful when we left, arranging for a taxi to the airport and coming by to coordinate everything at midnight.
In between, she suggested some outings and activities, helped us map out some walking tours, and in general happily shared her knowledge of local surroundings and things to do. When the power went out and the wifi was affected in the apartment, she quickly got on the phone and helped us get everything straightened out. What's more, we found her apartment to be quite conveniently located and more than adequate for our needs.
I would not hesitate to stay there again.
