I was in David's apt for 3 nights, it was perfect. David was waiting and ready for check in at the door of his apt. Also he guided us, where to go, where to eat, etc and basically make sure that we are enjoy lisbon. The apartment was so clean when we checked in, there is a tv with some good channels tho :). For the location, David's apt is wonderful! It is really in the central of lisbon! To Balem (to eat the legendary Portuguese egg tarts) is just about 10 mins by tram or bus, to tram 28 (You should have read about this tram online) is only about 7 mins by walk and surprisingly it is also around the governmental area, because we found the prime minister of Portugal' residence nearby!
