I visited Porto for 4 days and I choose Luis and Eugenia's appartment to stay. The appartment is great and you will find everything you need for your stay. Everything is really clean and well organized. The bed is extremely confortable and sheets are clean, that allow you to rest after a long day walking. The bedroom is quite far from exterior window so you dont really hear the traffic unfortunetly the bedroom is close to the main door and you can hear your neirbourghs if they are noisy. Luis was very helpful with some nice tips that allow me to spare some time. From the appartment you can walk to all main places to visit. For sure I recommend to stay with Luis and Eugenia. That will be my place when I come back to Porto. Obrigado Luis
