I can’t say that I was disappointed with my stay, but a few items made it hard to look back positively on:
1. The shower only has hot water for 1-2 minutes followed by 4-5 minutes of ice cold water. This was seen at different hours of the days over four separate days, so not just a single outlier.
2. No A/C means you have to sleep with the patio door open, which is a shared patio with another AirBnB. I was completely fine without A/C but did not feel overly safe/comfortable leaving my door wide open to strangers walking in.
Along with the neighbourhood being quite a distance from central Lisbon and the cleanliness being below average, I would probably suggest to keep looking for a different place. Again, for me there were no major dealbreakers here that made me pack up and leave, but it definitely might not match other people’s style.
