The flat is located close to the metro station and the airport in a lively neighborhood. Marcos and his family are very good hosts. The communication runs very smoothly, Marcos answers questions within an hour. I want to point out his flexibility as my schedule changed several times due to different reasons.
While his father and mother speak Portuguese only and I don't, communication was no issue at all. There are two cats in the building, they are gorgeous and funny. I strongly suggest to spend a little more time with this wonderful people (and cats) than I could due to my obligations.
