We stayed 3 months in this flat and it was great! Buenos Aires is a very noisy city, but in Emilio's flat it's really quiet, which was very pleasant. In general, the flat is smartly organised, which means that even though it's like a studio (only one main room), it doesnt feel that way.
The only thing that I would make others aware of is the internet. It's all right for just leisure, but i was working from home for the 3 months and I had a really hard time, as my conversations cut off often.
I would definitely recommend this place and I would stay again there.
Thank you for everything Emilio & Cecilia!
