We had a lovely stay here, great location in the less touristy bit of san telmo. The apartment has good AC, nice high ceilings and all the amenities you'd need. Sylvia was very friendly and brought us fruit and a French press to make coffee on arrival, showed us around and had good recommendations. The rooftop pool was also excellent, usually not busy during the week, so great for quick refreshment. The neighbors could be a little bit noisy, but nothing that kept us awake at night.
