I can't recommend this house enough. It's a real home away from home. Ignacio was out of town when I first arrived but his brothers were there to take care of things. Ignacio returned about halfway through my stay. All of the brothers are super friendly and happy to answer any questions you may have. The house is centrally located and in a good neighborhood. Public transportation and/or flagging a taxi is easy from the house. Norma, the woman who comes in and cleans is a gem.
If you stay here you'll have friends to hang out with, eat meals with, and will likely build lasting relationships with those around you.
I'm a host on Airbnb and Ignacio has given me several great ideas of how to improve my place.
I went on a walking tour of the BA street art. It was SO cool! http://www.facebook.com/buenosairesstreetart?ref=ts&fref=ts
I also studied tango with Alejandro Gee. Either of these activities I'd do again in a heartbeat.
You should definitely stay here when you come to Buenos Aires. Don't even consider another place!
Thanks Ignacio!
