My mom and I had a very nice stay at Andrei's apartment space. We arrived from the airport (about a 20 minute drive by taxi) about an hour before check-in time. The cleaning company was still inside, so we went to a restaurant around the corner until check-in time at 14:00. We got the keys from the Andrei's office and got settled into our place. It was a very nice place for the two of us... very clean, quite, comfortable, good location. Would definitely recommend!
I was able to get ahold of Andrei by phone and he was very responsive and helpful.
