We stayed in Mario's flat for 4 nights in October as a family. The outside space looks great but due to the weather we could not use it a lot. We should come back in summer months to enjoy this great outdoor area.
The flat was very clean and we did really enjoy our stay. Mario was so quick to reply it was almost like a live conversation so top grades here as well.
The location of the flat is simply perfect. Bakery, supermarkets, cheese shop, pharmacy all within 5 or less walking minutes. And to top it all off the Metro station just across the road. It is very convenient as with the line servicing this metro station you don't have to change when going downtown or even to the other side of the river.
The flat is well equipped and the layout is great.
Overall I can strongly recommend this flat to anyone who would like to visit Porto and of course I can also recommend Porto as well.
