We are in 6th district. The flat is very large, 43 sqm and it is fully yours to stay (maximum 4 people).
If you want to breath a good air, in a very peaceful, residential area, while still being in Bucharest, and enjoying the confort of a whole condo, then this is the best option. The appartment is sunny, air-conditioned and very quiet. There is a huge park near, and a bus station at the corner of the street. You can get down town in less than 40 minutes by bus and metro.
