We are a couple who stayed in Porto, at Sonia's house, for 4 days.
I cannot say that I recommend to stay at Sonia's place... the pros and cons are as follows:
- the location is very central;
- in the room you have a kitchenette, however useless in my opinion;
- the bathroom was not clean, there was hair (black and short) everywhere! The toilet was not clean as well...anyway, the entire bathroom :(. The bathroom indeed is not in the room, you have to go through a hall to reach it;
- the bed sheets was awful, they were in 4 colours I think, like 4 different pieces from 4 bed sheets; the room was fug. The bed is not comfortable. If I could to stay in hostel I think I would choose it instead of this house.
The room is in a house, which is entired shared with other tourists. And near you have a jazz or blues club, and sometimes is pretty hard to sleep because of the noise from there, or from the street.
