It was very nice stay for me and my husband - we came for a weekend in October. In old Lisbon you can see many numbered doors with super compact flats behind them. Anibal's apartment is one of them, so we liked the authentic experience. It is really compact and suitable for couples primarily, but you have there everything you need and in a good condition. Bathroom unit has proper ventilation, so its closeness to the kitchen wasn't a problem at all. You can cook, as you have stove and utensils, or you can go out - the flat is located really close to charming streets and squares with good places to eat. Actually, one of the Lonely Planet's favorite restaurants is just next door) It is really quite district (except for the airplanes above, but them you will hear everywhere in Lisbon), and you see real atmospheric Lisbon, with azulejos, balconies, etc. just outside your apartment.
