Fernando's apartment is a great home away from home from which to visit Buenos Aires and environs. The location is great in relation to all tourist sites, close to the Subte and numerous buses, a good variety of grocery stores, restaurants and pubs, and laundry.
The apartment and the building have good security and the Recoletta neighbourhood felt reasonably safe, even during the evening. There is a fair bit of traffic noise outside the apartment, but it is in the heart of Buenos Aires, so that should be expected.
We were personally greeted at check-in and check-out which was a nice touch.
