We visited Bucharest in March 2017 with couple of friends. Our host was kind, flexible and non-problematic person. Our arrival was quite late (2AM in the morning), but he did not make any problems. The place is suitable for bigger groups (like ours) and has everything necessary to stay there for couple days or even weeks. There are two bathrooms which is essential when there is more than 3 persons. No more bathroom fights in the morning. Apartment is clean, well maintained. Of course this not Ritz hotel, so please do not expect room-service or fancy drinks ;-)
Location is great. 2 minutes walk from old city centre, 1 minute to one of the best restaurants in Bucharest, shopping mall is across the street, bank and ATMs in the same building as this apartment.
Overall is great. I will definitely choose this apartment one more time during my next travel to Romania.
