I stayed for four nights in June, 2009, in the Residencial Estoril, located in Avenida Joao XXI in Lisbon. The area in which it stands has nothing especially interesting, but there's a subway stop and a bus right outside the door, so the transportation is excellent. The room was very small, with barely enough room to walk between the beds. There was a 14" TV on a small desk, but the room was so small that it was impossible to watch TV from bed. The bathroom was quite spacious, though, and had everything except a bath (just a shower).
The furniture was in good condition and the decor wasn't bad, neither beautiful nor ugly.
