If you don't know if this is the right place for you, let me tell you there is no better.

Pedro took care of us very well and was available the whole time via What's App for any questions. We arrived late at night and he met us at the apartment and helped with our luggage. All shops were closed and we were thirsty so he gave us a bottle of water (Thank you again!!) He checked back if everything is ok and gave some of the best advice.(check the view spots!)

The apartment is clean and in good condition. The beds were comfortable too ;) We felt right at home. You can easily walk to all the touristy spots, even in the middle of the night. We always felt safe around there.

Additional advice:
If you are German (like us) and need a typical German blanket just ask. We forgot to ask but we saw them in a closet when we left.
We really liked the
Cemitério de Agramonte
nearby. It is very different from German cemeteries and worth a visit. There is only one entrance so make sure you don't have to walk around the whole thing like we did ;) If you come from the shopping center you have to take a small street that goes through a building and looks a bit like an entrance to a parking spot.
Also the beach in Matosinhos is a nice sand beach. Take the metro or Bus 500 (about 30 minutes, on the weekend there is a night bus M13). The beaches south of Castelo do Queijo are rather rocky.

We liked Porto so much we had to come back a weekend later and even Pedro and Irene's rooms were booked out Pedro helped us to find another lovely place. You are really the best host anyone could ask for! Thank you very very much and say hi to Irene from us :-)
