We were 4 days in Lisboan for vacation. Really nice city, and the host recommend different things we should do and where to eat. The apartment was really cool decorated and had almost all we needed. All though there wasn't any air conditioning in the bedroom, so it got really warm in the night. The aircon was in the living room, and the bedroom was in the other end of the apartment, so it didn't help.
The host did also come home late at night and brought a "friend" (around 05.00 pm) they played music, so they woke us up. This was the first night we had in the city, so not a good first impression. But in the end we didn't see much to the host, so we got the apparent most to our self, and we got used to the heat in the night.
