Isn't AirBnB about renting a authentic home/room in the city you are visiting? This is clearly a money machine, and does not represent anything of a Portuguese home. Do not expect to visit a private home, but a "hotel" lookalike apartment, if you want something authentic find another place!
We did not meet Maria at check in or during our stay, she sent her colleague (not the one co-hosting on airbnb but a third person), he came 25 minutes late, and when he came he said the wrong name...
There is no fresh air in the apartment, it has no windows besides from the terrace door, and when it is summer you feel so uncomfortable due to the unbearable temperature in the apartment. No aircondition!!! The bedroom is placed in the middle of the apartment, so there is no chance to get fresh air in there either, causing a very bad sleeping environment.
The apartment were not at all clean, there were dust everywhere, insects on the walls that had been slapped. I guess there has never been a vacuum cleaner underneath the bed or beside of it. The bath was ok.
The doorways are very low, so if you are a little tall, be prepared to bump your head everywhere.
There is a lot of noise, as you can hear everyone besides or above talking and walking around. And also the apartment is placed in level with the road so you can hear every car that drives by...
The bed was really hard, and it all looks like something from an IKEA catalogue.
Maria, was not really serviceminded as there where some confusions, and I do not think it is worth the money at all.
