Lovely stay in Porto, apartment is close to all of the sights, within walking distance. There are some nice restaurants and cocktail bars close to the apartment, supermarket and metro station (which has a direct line to/from the airport) are all within a few minutes walk from the apartment.
The check-in process and communication with the host was very easy (the apartment is located on the second floor not the ground floor).
The apartment was very well furnished with everything you need for a short stay, the bed is a little firm but not uncomfortable.
As mentioned in previous feedback the TV seems to be stuck on one volume and seems like this cannot be changed, also noise can be heard from the apartment upstairs (floorboards as people walked around).
