Place is within walking distance from Intendente station and Martim Moniz. There are several shops and restaurants on both sides depending which station you use, many of these are Chinese and Indian and deserve a visit.
The apartment is on a second floor this is a walk-up so don't expect and elevator, I recommend if you go out or comeback at night to use the flashlight on your phone as at the moment of my visit there was no light on the entrance or the staircase.
The apartment in itself is small with a small closet but it's good enough for two people with two carry-on luggage. There is a balcony that faces the street but we didn't use and kept the metal blind half way and window open otherwise apt will be flooded with sun which made room hot as there is no air circulation or air conditioning. There is a lot of noise coming from the street that might disturb light sleepers we are new yorkers so it didn't bother us.
Overall place is clean, central and economic just consider what I mentioned before to make your decision. The host meets you in the apartment and gives you the tour and keys he is a friendly person and easy to communicate with.
