Hello! We spent 5 days in Lisbon in March. Hosts are very helpful, answer quickly, there is no problem with check-in and check-out, no matter at what time. The apartment is in a great localization with the convenient communication. Maybe because it was March, the apartment was moist and a little cold. So it’s not the best choice for the people with children during the cooler months. There are only 2 windows - in the kitchen and in one sleeping room. The other sleeping room has no window. During the summer, there would probably be no problem with moisture. Thanks for all of the advices, wish you the best!
