We had a great time in Frederico's apartment. The location is great. it is walking distance to tons of bars, restaurants and cafes and was very quiet. This was a definite plus for us, because we didn't want to stay in the middle of someplace like Bairo Alto; this apartment afforded us very close proximity to all of that, but allows us to retreat to someplace much more quiet and peaceful.
The apartment itself has everything you need for your stay and communication with Frederico was prompt and friendly. Any issues we had, he addressed almost immediately.
The only downside could be that the apartment is in the first floor and directly across the street from a school and there are always students walking around outside during the day. At times this can cause you to feel observed, but during the day when the sun shines no one can really see into the windows.
