I stayed at Miguel and Florencia's place for four nights and can highly recommend it. They are fantastic hosts, gave me lots of recommendations and helped me with all my questions to make sure I had a great stay. The room is nice and had everything I needed and the ensuite bathroom is an added bonus, as is having breakfast in the sunshine on the balcony. The appartment is in a nice part of the city with lots of shops and restaurants nearby and only a few blocks to the Subte.
