The welcome of the host has been well organised and she was available to welcome us slightly earlier than how was written in the advertisement; moreover she provided us a free map of the city, that was really appreciated by us.
The location is great: the house is in the middle of the city centre, and you can reach really easily all the transportations (tram, metro, trains towards Sintra and Cascais). The only inconvenience of being in the centre is the noise that can wake up noise perceptable people at morning: if you visit the city in summer, you are obliged to let your windows opened at night; the first tram early in the morning (6 am?) inevitably makes much noise. This seems to be quite common in Lisbone, as the tram network is rather developed.
The house is comfortable, and has all what you need for a good staying. The main bed is quite short, then for tall people is not the best one possible; on the other side, it is also really comfortable.
