Helpful professional hosts, they rent many properties in Lisbon. They reacted promptly when we pointed out the dead bulbs in the bathroom or on the landing. The shower was blocked and we hope it will be fixed for the next guests. The flat is in a rather cheap touristic neighbourhood with many youth hostels (one adjacent to the building). It is not very attractive but it is central though. The flat itself is OK although a bit weird with the staircase walls literally obstructing the living room. The bathroom doesn't have a single hook for the towels. But my main issues is the bedding. The mattress is really bad, the bed sheets too small (would not tuck underneath the mattress) and the pillow are the worse I have ever seen: flat, synthetic and hard. And the traffic noise doesn't help as it is on the 2nd floor and not well isolated. You have to bring your own pillow in my opinion.
Finally the wood floor is noisy and this was particularly noticeable when our neighbours above came back in the middle of the night and woke us up with their steps.
