We (myself and two friends) spent 3 great days in Oliviers very well equipped apartment in a quiet street. It has a great living room, full of light, with three big windows, small balcony and with a beautiful view. The beds are very comfortable and is was very convenient to have two bathrooms. Also the kitchen is high standard. Príncipe Real is a nice area near the botanical garden, with a lot of shops (design) and restaurants. It's a quiet neighbourhood.
The contact with Olivier was pleasant and easy. At arrival a very nice lady waited for us and showed us around. She even brought us some coffee and milk. by phone/email she was available for all questions. to stay there is very recommendable!
