We spent two days in this appartement. Communication before arrival was very good. The hosts were extremely friendly and gave us many useful recommendations on what to do. The location of the appartement was very nice. When arriving, we were welcomed by an employee. Communication was hard because he only spoke Portuguese which we didn't. We expected the appartement to be larger and were surprised that it was extremely small, definitely too little photos on the page that shows the room. Also you couldn't fully close the bathroom door which was exactly next to the kitchen (therefore not very hygienic). If you travel with someone else, make sure you are comfortable enough with them since it literally feels like you're in the same room with them when they're on the toilet.
Overall, for two days the appartement was okay but if we came back to Lisboa we wouldn't book this appartment again.
