Joao has been very responsive and helpful throughout the whole process. Unfortunately we didn't meet him personally but a friend of his was so nice to pick us up from the airport for a good price and introduced us to the flat. I have to say this place is really nice and modern and we had a great time there! The only two negative things I could say are that the room wasn't ready yet when we were there after 3pm (but not a big problem at all) and that once the electricity went (which is quite common for Portugal though so also nothing horrible just a bit annoying when it happened). Other than that everything was great. Joao even bought wine for us which is lovely. The flat is well equipped, modern and cosy, perfect for someone travelling alone or as a couple. Also the area is brilliant. We could walk literally everywhere so I would really recommend this place :)
