My wife and I stayed here for a week. Honestly, the only really good thing about this place is it's location. The apartment is comfortable enough, but it had one major problem that is hard to overlook in a week's stay - the shower. Host tried to convince us that if we were "careful" with the curtain, the water wouldn't leak out. My wife is a fairly small person and no matter how "careful" she was, it was nearly impossible to keep water from spilling out and flooding the bathroom floor. Needless to say, I had a 0% success ratio with this.
Host is OCD about optimization. She allocates an exact number of rolls of toilet paper and getting more rolls requires her approval. Kitchen includes no basics such as salt or pepper. Check-out was 12:00 PM and we told her we would be leaving at 11:50. At exactly 11:51 she messages me that I can leave the apartment, literally as I'm in the middle of opening the door...
Bottom line, there are places in Lisbon with good hosts, better facilities, in a similar location, at roughly the same price - your money is better spent elsewhere.
