The apartment was very clean, modern and tidy! It's next to one of the biggest sights of Porto, Sé Cathedral. You would expect it to be busy with tourists but that's not the case because the cathedral is on top of a hill. Therefore you have a great view but you also need to walk up a hill whenever you go back to the apartment. Thankfully the church clocks stop at 11 pm until 8am.
We were surprised that there was no separate bedroom. Based on the pictures you would assume that. However, the bed comes out of the wall and lies on top of the couch.
If you don't mind the hill or the (wall)bed, I would recommend this apartment for your stay in Porto!
