Carla was not my host but Marieta. She is very friendly.
The apartment is very good when it comes to location and facilities. The location with the Alfama neighborhood just around the corner is very attractive. The facilities in the house are good. There is a problem with the keys. So far so good. The big problem with this apartment is the noise from outside. As many Lisbon apartments the front door opens directly to the living room. And the only window is above this door. So the noises from the street with cars, buses and people walking by are already substantial. Above all the upstairs neighbours are very noisy, walking like elephants from early morning till late in the evening. Then there is a lot of building (drilling) noise from the opposite houses. Furthermore every early evening people gather at the social welfare center just a few houses away leaving very loud barking dogs outside. At last there were sewage reparation activities with roadwork during two days of my stay. Only the last activity was incidental. The rest seems quite structural when I read the review from guest in October. Unfortunately this review was not available when I booked. Marieta was very empathetic and messaged the owners about the problems. From the owners I heard nothing. So my conclusion is: only go to this apartment when you go for the location and buy a bag of earplugs!
