Mario was very responsive, responded to our messages quickly and was very helpful. The airbnb is in an atmospheric old building and it has a great terrace, which we used to practice yoga. The room has terrace doors which was great. We liked the location of the place, almost on top of the subway and walking distance from the major sights in Porto. (Mario has an app which points them out, we can recommend it!).
Mario has made an effort to furnish the house in a modern way. It is a five bedroom house so there are a lot of guests. All the other guests were respectful can quiet when we were there so we had no problems.
The wifi connection was very good but did not reach all the way into our room, however we discussed this with Mario and he will look into it. Mario was very open to feedback, a lovely quality in a host!
Breakfast is complimentary at a cafe nearby. We made use of this every day and we really loved it! It's only a short walk away and it's a nice little cafe. All in all a great stay in Porto!
