I really enjoyed staying there. Juan and his wife are excellent hosts. It's not a five star hotel, but authentic and offers you an insight of buenos aires away from the touristic barrios like palermo.. yet I still felt safe, also alone in the night.
And despite being not veeery central, you can reach with busses the metro, taxis or uber almost everything within 30, 40minutes.
Price per value is excellent, and although some items in the kitchen or bathroom are a bit old in the house, everything worked perfectly!
So, thanks again for the nice stay :)
