We stayed at the corner house for 3 nights. Didn't get to meet Carla but she kept in touch and was very helpful.
The apartment is clean and as showed. Size wise, it is comfortable for the 2 of us but @ 5.3" tall, I find myself ducking around in the bedroom due to the low, wooden tent like ceiling and find the washroom to be a little small to what we are used to. We didn't use the kitchen but most of the necessities are provided for.
This apartment is very conveniently located with just a few minutes walk to the central. The neighbourhood is interesting with many small convenient stores, restaurants and pubs. At nights, it became very lively and crowded with mostly youngsters and tourists hanging out to drink. They ain't causing trouble but very noisy till early morning. I was prepared (based on past reviews) and used earplugs.
To me, it was a good stay and it allows us to experience Lisbon. For those who are very sensitive to noise (like my husband), the noise might be an issue.
