We had a beautiful experience during our trip in Portugal and we spent 4 nights in Rodrigo's apartment. The flat is in Barrio Alto, extremely central. Unless you are in a noisy area, the place is quiet and you have wonderful views through its balconies. It is on the 5th floor without elevator (if you want to stay in a Portuguese hystorical city center it is a common characteristic) but it's worth it. The apartment is clean. We never met Rodrigo but he answered all the questions during our whole stay. Both him and his father made us feel welcome.
Overall, I would thoroughly recommend the host and apartment. I would definitely stay here again.
