I spent a few days short of a month at Claudia and Ricardo's place working remotely and was very satisfied with everything overall. The WiFi is stable and fast, the AC was much needed and worked perfectly. The flat is small but ideal for one person to live comfortably. Bed was comfortable and neighbourhood is surprisingly quiet even though the most popular restaurants and bars are within walking distance.
The laundry room is cheap and easy-to-use and wet clothes may be air-dried on the huge balcony. There's also several well-equipped gyms in the area as well as a tiny gym in the building (treadmill and a multi-purpose machine, nothing fancy) next to the shared pool.
I arrived at Baires very late and Ricardo was able to assist my check-in in return of a negligible late check-in fee.
