I enjoyed my stay here a lot! The studio is spacious and located in a quiet street in a nice neighbourhood. You can easily reach any place in Baires thanks to lots of colectivos stopping close by. Café Le Blé across the street offers fantastic bread (which is not easy to find in Baires ;)). For tango dancers: La Maleva and dni tango are just a few minutes away on foot!
I didn't meet Fernando in person but communication with him via eMail was always very helpful, prompt, friendly and pleasant. Fernando was very generous in letting me move in earlier and letting me stay until 8pm on my checkout day.
Andrés who is taking care of the place in Fernando's absence was there on time we sceduled on my arrival, so very reliable as well.
Due to barking dogs (they are EVERYWHERE in Baires), do bring your earplugs if you're a light sleeper like me. There is no laundry machine in the studio but I paid only 40 Pesos in the laundry service around the corner and they had my things ready ready within a few hours.
Wifi worked flawlessly. Bed is comfortable.
Would definitely stay here again.
