Maria and her husband were very flexible with the check-in and check-out time. They were even waiting for us as we arrived a bit later than expected. They welcomed us with a couple of pasteis de nata and left some beer and water for us in the fridge.
Maria was informed immediately that the WC was a bit dirty. Same goes for the shower and the sink in the kitchen. We also found a juice box on the wardrobe in the bedroom and a glass of water left on the window. She apologised and said it was because the previous guests left the house very dirty. I was expecting something more as she also asked for additional 20 euros for cleaning expenses.
Also, I was a bit disappointed to find that she did not think about leaving some spare toilet paper, ad when I asked she said that we had to buy it.
The host does not speak English and she always replied in Portuguese to my English messages. I don't speak portuguese, and sometimes even Google was not very helpful with the translation. Anyway, we understood each other, more or less.
Apartment is at least 20 minutes walking from the heart of Porto (and I am quite a fast walker). The area is anyway nice and safe, with some shops and a supermarket not too far. Closest metro station is 10 minutes away, and there is also a bus going to the centre.
All in all, it was not a bad experience, but I would recommend the host to pay more attention to basic things (such as cleaning) than to frills (a lot of decorations in the flat).
