We were 5 adults and a child staying at Alexandra's apartment and it was more than adequate for us. It is smartly furnished and very welcoming , and the terrace is a bonus. We didn't get to use it as much as we wanted though due to the weather and time constraints.
The beach, shops and resuturants are within walking distance which was really great. There's a taxi stand on the left corner as you exit the apartment building which is very handy. And the subway station of Siqueira Campos is less than a 10 minute walk away and very easy to use and cheap. We took the subway to Gloria for the Selaron Steps, Cathedral, Arcos de Lapa and the Confeitaria Colombia, and returned from Carioca. We used the subway again to visit Santa Teresa the next day. There's a wonderful bakery a few doors away where we got fresh bread and other goodies in the mornings.
Alexandra was very kind and allowed us an early check in and a late- ish check out which we greatly appreciated. Andrea who looks after the apt was also prompt with greeting us and checking us out. And she was also prompt to respond when we informed Alexandra of a minor issue. The apt was also tidied once during our week long stay which was great.
As someone else has mentioned, the shared shower is quite a tight fit and the separate loo is in a lobby off the kitchen. It worked out ok for us .
Oh, I noticed in the photos that there was a Nepresso machine and as we also have one, brought along a supply of capsules. Also appreciated the well equipped kitchen.
All of in all, we had a lovely time and enjoyed the wonderful city of Rio!
