The only good this about this place was the host, but unfortunately that wasn't enough. I arrived as a solo traveler, after easy and pleasant communication with Jose.
A neighbor gave me the key and showed me the way to the 2nd floor apartment. I thought it was 1st floor, and I had no idea these were the steepest stairs I have ever seen in Lisbon (and I've seen my share of Portuguese stairs). It was almost impossible climbing up with my luggage.
The apartment was not as nice as in the pictures, it was old, somewhat stuffy, not in great condition, and the noise midday was concerning, but the real issue was how unclean it was: Hair (the worst kind) everywhere, stains, including of #2 in the toilet! (sorry for the description)
I told Jose I don't know what to do, and he said he cleaned the apartment himself some time ago, and being away he guesses that means someone was in the apartment without him knowing about it. He suggested I leave, and provided me a full refund, which I appreciated.
