Centrally located & walking distance to all sightseeing places.. Had a tough time trying to open the door to the apartment, figured out after couple of days.. definitely need some work there. Also didn’t know we had to ask for sheets for sofa bed, which was not provided on the day we checked in. I booked this apartment since it said two beds, I was traveling with my friend & assumed when it said sofa bed it came with sheets.. Other then that the place is very close to Douro river & a happening place. Communication was excellent!
