Rocio and Fede are the best. Really went out of their way to make sure I had a good stay and very communicative. Both speak excellent English. Apartment has everything you could want. The location is great, the apartment is quiet at night but with restaurants and bars within walking distance open at all hours, urban but not overwhelming. Subte is a quick walk and if you have any questions about what to do in the city Rocio will provide you with some great suggestions. Couldn't have asked for more.
