We did not get to meet Rodrigo as he was out of town when we arrived, however, he arranged for his neighbour Teresa to greet us and she was more than helpful - She gave us a map with locations highlighted and instructions how to get there, which days were best to go, which public transport to get, markets that were worth checking out, restaurant recommendations and even booked us a taxi to the airport for when we left.
We had to keep the shutters closed to shade the apartment as it was very hot, so it was a little bit darker that it looks in the pictures, but it was very clean and had everything you could ask for and more - The free wifi was a godsend and there was tea and coffee and shampoo etc provided.
Location wise, we thought it was going to be slightly closer to Belem (it is about a half an hour walk away) but it is very easy to get into town using the buses and trams - and a taxi was only about €6 from Barrio Alto. It is also walk-able from Alcantara-Mar station (about 15 mins) so a good location overall.
For the price, this is a really excellent stay. Highly recommended.
