Marcos flat is a nice one in the inter of Lisbon. It's not directly in the centercenter but just a few minutes walking distance to all the attractions you want to see. And the best thing is you can park for free if you've got a rental car. the flat was clean and cosy and you could see that Marco spend a lot of time arranging the interior details (stuff from flea markets for example). We just saw him for a few minutes but seemed to be a really nice person. would recommend him as a good host to stay in Lisbon!
