I had an extended stay in Fabiola's flat and found it to be a home away from home. Fabiola was very quick to respond, and always very friendly and professional. Her mother was at the apartment to greet me upon check-in, and even allowed me to check in early. The apartment was very clean, modern, and comfortable. The internet and A/C worked very well. The kitchen was a bit difficult to use for someone like me who was staying for a long period of time, but if you don't plan to use the stove and kitchen, then no need to worry!
There is a lot of morning light which was great, and a nice view of the park below.
I would definitely stay here again, and would recommend anyone to stay in Fabiola's flat when visiting Rio!
