We stayed at Ana and Ricardos apartment for a month. Yes the view is amazing and the apartment is in a terrific location, Ana is very welcoming, has lots of recommendations and is great with any communication and issues. There is no elevator so if you are challenged physically, being on that top floor with all the stairs may be a real issue. The apartment is very small but comfortable. A long stay wishing to cook may be disappointed with the kitchen and what is available. I had to purchase dish towels, a small chopping board and a small pan as the available non stick pan was destroyed to the point it was dangerous to use. Also, it would have been nice to have had more than 1 wine glass and 1 regular glass. The available clothes rack for drying is rusted badly so rust stains on clothing was a bit annoying. Unfortunately we did have a few cockroaches but being this is an older builder...? There is a laundromat is within minutes. This is a great area, lots of restaurants very close by and an easy couple minutes walk to buses, and Santa Apolonia station for metro and urban train services and a small but decent grocery store.
Wonderful hosts, however, I don't think we would stay here long term again. Great for a couple of days.
