This was our first experience with Airbnb. The host Victoria is very warm and engaging and provides very helpful advice on how to explore Buenos Aires and she was very responsive to dealing with any questions we had or matters that required her attention.
There were a number of helpful points that made our stay easier, for example, it has a washing machine, a point that is not obvious when looking at the description, which says there is one in the building but does not specifically say it is in the apartment. Victoria provided two Prepaid Cards to the subway system (SUBE cards), with sufficient funds loaded to at least enable us to ride the subway and think about adding funds later when we better understood how the transport system worked. A mobile phone for making local calls was also made available, a very helpful addition for those who don't have a local SIM card. The internet also worked well.
The location is very good, being within easy walking distance of Callao station on both Lines B and D. The restaurants in the immediate area are fairly average and not that numerous. However, Victoria had a number of helpful suggestions for better quality restaurants that were not that much further away and still within a reasonable walk or a cheap taxi ride.
We felt safe walking around the area.
