This is a fantastic apartment in a fantastic neighborhood. Palermo is my favorite place in BsAs, and this place is within a couple blocks of all the restaurants and bars, but not so close that you're bothered by the noise and crowds. Ricardo is a wonderful host, super communicative and helpful. The unit is on the 9th floor, which means you get some amazing views of the city, and are really close to the pool/gym. But, it also means you're right below the community parrilla on the 10th floor and you'll sometimes have a little noise from people moving chairs/tables around when they're grilling. This never bothered me at all, but if you're the type to go to bed early and sleep light, something to keep in mind. The building staff is friendly and helpful, as are the other residents.
Wifi was solid and fast throughout the stay. Had to restart the router once in the month I was there (less than I have to restart mine back in the US).
Great place to stay!
