Nice building in alley with entrance from Seleron staircase, very close to Lapa and all the fun, yet quiet at night. Security seem pretty solid, there is big gate at the beginning of the alley that get locked at night, and metal door at the entrance to the yard.
I was in apartment that had all basic appliances, TV and good air conditioning (very important), with access to shared balcony and roof with nice view of Santa Teresa and Lapa. It looks exactly like on pictures. Cristina was not in Rio at the moment, but Francesco was there to welcome me. He speaks good english and was available when I needed something.
Make sure you get familiar with house rules at arrival, specifically if you are foreigner, because some things are very specific to Brazil.
In my opinion it is good value for money, especially in time of Carnival when all prices go up. Good for digital nomads (like me).
