First of all I want to thank Marcia for being a wonderful host. She gave us a lot of useful information and was always there when we needed her.
The apartment is really nice, situated in the center of the party district. You don't even need to take a taxi, all the cafes and clubs are at walking distance. Also there is a grocery store next to the building, so it is very convenient. The apartment is very close to Arcos da Lapa, actually you can see them from its window. Moreover the Escadaria Selaron is around 10 min walk far from it. So you can visit some of the sightseeing very quick :)
It was very pleasant to stay in the apartment and have such a nice host.
Thank you Marcia :)
