I stayed 6 weeks and this was perfect for me. The wifi was fast and no outages which is important to me. I have stayed iat other Air bnb's in Buenos Aires and wifi was unstable and often did not work.
The location was great, entrance on Lavalle which is a vary safe area. Close to good restaurants such s Las Inmortales, La Estansia....
Jorge who is the local contact and lives in the building and Maitee were great.
