This apartment had positive reviews and looks very lovely in photos. Unfortunately, some things you just can't tell from the photos and those issues really spoiled our experience. Overall the apartment has a smaller and darker feel than in photos. It's a ground level, so we had to keep curtains closed for privacy which made it darker. The bed is very small, less than a standard double mattress and short. We are not big people btw, but two people can't comfortably sleep on it. My partner slept on the couch the whole week. The place is very damp and humid with sewage drainage issues. The whole apartment smelled like sewage despite running the air conditioner and buying extra plug in air freshener. Smell came from all the drains. The host told us it's a common problem in Lisbon in the summer, however none of the people we met who rented apartments had similar problems, so I think it's safe to say you can find a place that doesn't smell this bad.The bathroom had black mould stains on walls near the floor and ceiling (we took photos of those). Also, the wi-fi signal was very weak. Unless you are on the couch it would occasionally cut out in other corners of the apartment.
We suggest staying somewhere else even if it means spending a little but more money.
Nothing personal against the hosts, but we were very disappointed with our stay because of the issues I described.
