Felipe's apartment is great! We stayed for 3 weeks while working remotely and really enjoyed our time. The apartment is new, bright, quiet and well equipped. The internet was very reliable. The AC is a big plus. There is a laundry room on the top floor that you can use - useful for a longer stay. The neighborhood is nice and quiet, there are supermarkets, restaurants and coffee places close by.
We would definitely recommend it and it will be our first choice if we need a place to stay in that part of Buenos Aires again.
