Our stay at Mila’s place was very pleasant. The apartment is nice and well equipped. Proximity to the train line is a plus although it makes the apartment a bit noisy. We had everything we needed and there are plenty of places to eat around. Mila is a great host, replied very quickly and is very accommodating (our flight was late in the evening and as the apartment wasn’t booked for the day we were leaving she allowed us to check out late).
There is a booklet with suggestions of places to visit which is helpful if you haven’t visited Buenos Aires before.
Overall, a very positive experience, recommendable.
