Lisbon is an amazing city and the location of this apartment couldn't have been more central! The famous tram 28 passes right under your window so if you are light sleepers it might be a problem, however we found it rather charming and you really get used to it after a day. The flat is small, but enough for a couple. It is very tastefully decorated, we even got some ideas how to refurbish our own flat :) I wouldn't recommend drinking the tap water, there is a small shop right across the street where you can buy mineral water rather cheaply. We really enjoyed our stay in Rui's apartment and in Lisbon and would recommend it to our friends :)
