The only good thing about this place was the kindness and understanding of the host, but unfortunately that is not good enough.
I arrived at the apartment after easy and nice communication with Pedro. A local neighbor showed me in, it was around 12 steep stairs up the first floor, very accessible.
The pictures of the place are much better than reality. In practice, the place is old, not in a great shape, not enough lighting, and not comfy or cozy. The bathroom faucet is all rusted, so are other bathroom tools. But what made me ask to leave the next morning, was how unclean it was: From hair (including the worst kind you can find) everywhere, to itchy linens and blanket, dirty rugs around the house, dirty sofa, sticky floor and table, and more. I found myself trying not to touch anything, and after a sleepless and miserable night, I asked Pedro to leave and he kindly accepted my request.
In conclusion, I think the place is not a great value for money, as it was leaning towards the expensive side fr Lisbon and still was quite old and not comfy, but the deal breaker here was how unclean it was. Shame, because Pedro seemed like a good and caring host from our communications and his willingness to cancel my reservation. Still, it definitely ruined part of my trip, which I wish would have been avoided.
