We had a good stay in Porto. The apartment was nice, clean and well located. The check-in went smoothly.
Some things can be improved. There are some things that were missing, which are usually cheap, but important to travellers: some salt, pepper and some kitchen towels. Also, the coffee was really bad - for this price and based on our experience with other hosts in this price range, our expectations were a bit higher.
With all this said, I recommend this place to stay for other travellers.
