We had a very nice stay at Juan's place located directly at the castle. The area is nice with cute little places and some good restaurants/bars although I wouldn't recommend the area for older people or people having problems to walk (many stairs at night). The flat is tiny but very cozy, so perfect for a stay of two people (but not more ), just as desribed. Juan was super helpful: he recommended a couple of very nice restaurants in the closer area, gave us good information about travelling in Lisbon in general and explained public transport etc. to us. He was the perfect host, showed flexibility with the key exchange and provided us with a perfect accommodation for a long weekend in Lisbon. We will come back for sure.
