Maria’s place is super cute!! It’s a nice cozy area and not too far from Porto center... it’s about a 30 minutes walk which is not too bad. Although the roads are a bit dark and empty at night, it still feels fairly safe.
Maria is so thoughtful she will check you in in person and give you a map of Porto and explain to you some of the popular tourist spots. She is also responsive when you have questions. Definitely recommend this place.
The only thing to keep in mind is that the hot water is limited so don’t take too long of a shower.
