The location is perfect. Not only it is right in the center, it is also not on one of the hills so no need to climb to get to, which is a blessing in Lisbon... The apartment is fairly small, but has all you need and everything is new and spotless. As others have noted, the noise from the street stops at around 11pm so did not bother us, though we were a bit bothered by the noise from the apartment upstairs early in the morning. We did not meet Rita and Helder personally, but they were very helpful and responsive and provided good advice. They also arranged for a friend to pick us up from the airport which was very convenient and he also provided great advice on the town. Overall, great place to stay in Lisbon
