The staff at Welcome2BA were friendly and helpful when I arrive in Buenos Aires. We had a slight snafu with the key hand-off, but they resolved the situation quickly and agreed to let me stay a few hours past the check-out time of 10am the day I was leaving. Once I was in the apartment, my only contact with Welcome 2BA was their automated emails, one of which reiterated the 10am check-out time (I ended up staying till the agreed-upon time and didn't have a problem, but the email caused a bit of stress). The apartment itself has nice and relatively spacious common areas (kitchen, dining room, living room), though the bedrooms felt a little cramped and the decor is austere. The location is excellent--in the heart of Barrio Norte/Recoleta, close to restaurants, parks, and the subte on Santa Fe.
