A great place with 3 bedrooms and a terrace, perfectly located at the top of Porto's historical center, 2 minutes walk away from the Torre dos Clerigos, the Lellos 'Harry Potter' bookshop and the University. There are numerous restaurants and bars all around and being at the top allows you to easily reach any point of the city.
10 meters down the street, you'll find a great viewpoint on Porto, overlooking the historical city and the Douro and about 5 minutes walk away you'll find the Miradouro das Virtudes, a nice viewpoint and great place to enjoy a beer after a day exploring (it can be crowded, especially around 7-8pm but dont let it turn you away, the atmosphere is great)
Note that the bedrooms dont have exterior windows but this was actually nice to sleep in :-)
All in all a nice flat with a great location and the team takign care of it has been very responsive and helpful with any issues we had (Note that the outside key does not open the door directly next to the lockbox but the one on the right of it)
