This flat is perfect for a couple or two friends. It is compact but not too small. It is well decorated and has all of the usual amenities that you require. A short walking distance to either two metro stops. The sound proof windows and air conditioning really help with sound because at night it can be lively but not out of control - very civilized.
Highly recommend staying here. Note however there is no elevated and the stairs are a combination of wood and stone (which can get very narrow).
For any North American travels, make sure that you get a 'lesson' on locking and unlocking the doors. If you have travelled in Europe, then you'll know that the locking and unlocking of doors is quite different from North America.
Enjoy your stay!!!
