I cannot say enough about our experience in Porto and this flat.
Communication with the host was excellent. They even recommended great places to eat and see. The Port wine and wafers were a special, appreciated touch.
The location of the flat was ideal. It is within walking distance to old town, stores, restaurants and metro station. Uber/Cabify to get around is very inexpensive and easy.
The flat itself is very clean, modern and comfortable. We felt safe in the area. We were a group of three and there was room for more!
I would definately return, stay here and recommend this flat to anyone. ;-)
