We really liked our experience with TPC. All essentials were provided as well as an additional gift ;) The flat is conveniently located, close to main spots, pubs and clubs, yet at night it was rather calm and quiet. There are electric heaters and fans in the flat, as usually in that area flats do not have any central heating. There is no lift in the building, but we didn't mind climbing the stairs (2nd floor). Both check in and out were really easy, and communication with the office before and throughout our stay was excellent. Yet by our mistake we needed to change the number of people in our booking the same day as we were about to arrive, what was impossible. The office did not want to offer us any assistance with solving this issue (probably they'd never faced it before) and redirected us to Airbnb customer service line. After we called the CS they admitted that solving such a problem is much easier from the owner's side than from the customer's, so eventually at our request the Airbnb contacted the owner and guided them how to change our booking. Overall, we were glad of picking this offer and we will definitely stay in one of their flats in case of other future visits in Porto.
