This is definitely the place to stay in Buenos Aires! My boyfriend and I had the best two weeks here. The flat is in a great location and has everything you could ever need, including very welcome air conditioning and a beautiful balcony to soak up the balmy evenings. Tomas went out of his way to make sure we were settled and comfortable, and went above and beyond by helping us book taxis and even storing some of my luggage a little longer so I didn't have to lug it around with me.
Wouldn't hesitate to recommend and would definitely stay again if I am ever back in BA.
Gracias por todo Tomas!
