Tiffy and Marcelo make wonderful hosts. They were very welcoming and gave us a lot of information. They even bought us some water and milk in the fridge, which when you arrive at night, was greatly appreciated.
The apartment was close to the centre of Recoleta, a very nice suburb of Buenos Aires and the flat is exactly as pictured and very comfortable.
On the last day, Tiffy went out of her way to help us with a private problem we needed sorting, as we don't speak Spanish. So thanks again to Tiffy and Marcelo for their help.
