We stayed with Griselda for 4 nights and everything was like we expected! The apartment is central and right above a subway station, which is handy but you are not noticing it at all. Griselda is really nice and friendly and told us what we have to see in Buenos Aires or what would be great for a kid to see(we travelled with one). So even though there was a problem with the lock on the door, it was fixed fast. It is definitely worth staying here and this made our Buenos Aires trip better. (:
