Everything was 100% correct, the communication was very quick and fluid, very flexible on the check in/out times which was greatly appreciated, the apartment was really a great location, very central but still quiet, it was clean and everything as expected - the kitchen is without a cooker which I didn't remember but we were eating out all the time anyway so it didn't matter to us and there was a fridge, a coffee machine and water heating facilities so all that you need for a short stay.
Very impressed by Oporto, very nice city, if I return I will definitely look up Pedro again to stay at his apartment.
thanks again!
