I appreciated the way they handled my flight delays that changed both check-in and check-out times.
The communication with the host and the person who was waiting for us was very good (email, whatsapp).
The apartment is tastefully decorated, with everything you need, you really feel "at home". The beds are very comfortable.
It has no air conditioning and can cause discomfort during hot days. But in every room there are fans.
The location is very close to the Anjos metro line but there are also connections for tram 28 or buses. There are many restaurants and dining places around, Auchan/Lidl supermarkets outside the small markets.
The apartment is located in an old building, tiled with Portuguese specific tiles. It has probably been completely remodeled to create 2 bedrooms and a living area. It really isn't well soundproofed, but in general, the neighbors observed quiet hours 23-7.
If you do not want to stay in the tourist commercial part of Lisbon but to live a Portuguese experience, I think it is a very good choice.
