We spent three nights at Ruy's place and really enjoyed our stay.
Ruy was a great host - very easy to communicate with. He provided transport to and from the airport, and gave us some very good suggestions on where to eat, barrios to visit at different times of day.
The apartment was clean, had all the basics you could want for a self-catered stay and the terrace is great for breakfast. It's centrally located in BA - 5min walk to Moreno Subte station.
The neighbourhood is a regular BA barrio - safe, with a good supermarket around the corner, some good local restaurants and a great cafe run by 3 viejitos on 9 de Julio and Belgrano.
Will definitely look up Ruy's place next time we visit BA but will also check out his other joints as well.
Thanks Ruy for being a great host.
