Excellent location, Trindade metro station is nearby, easy to approach to either Campanha train station or Porto airport from there, also is not far from all main attractions of Porto. 2 supermarkets nearby, easy to get living supply. Cozy and very nice view in the apartment make you feel like lived in a relaxed contry side. The apartment is not big so it may not suit you if you require a spacious place to stay. No elevator so if you carry a big luggage, you need some effort to take it upstairs or downstairs.
Would love to stay there again when I visit Porto.
