Gustavo has the perfect personality to be a host; helpful, friendly, fun, warm and funny. He gave me lots of tips that were helpful in terms of how to find things. I do wish there were more restaurants near his place but in contrast to more touristy areas, there were many stores selling items that residents of Buenos Aires need rather than just tourist shopping so walking around the neighborhood gives one a better idea of the city than just staying in tourist areas. The apartment is well appointed and very comfortable. If you have chemical sensitivities or asthma, do let Gustavo know ahead so that he doesn't spray the mattress with disinfectant; I'm sure he'd adjust. A really nice stay!
