We can highly recommend Tiago's place. He was very supportive during our stay in Porto and help us with our questions or needs f.e. Bring to us weights to check how heavy is our luggage. Apartment is in good distance to city center to via Santa Catarina it's around do 10 minutes walk. Near the bus is also main bus stop where lot of distance buses are staying and underground is approximately 5 minutes walk max. Apartment was clean and really nice. If you do not need kitchen this room is the right for you :)
