As a telecom customer you apparently have no network in Porto so I had asked Luis if I could have the check in data. This was apparently a problem and it went back and forth and back and forth. Until he finally sent the data 20min before check in. And I had the struggle for the first six hours to find wifi spots to see if he answered. Also, I had written to him right after booking and he replied six weeks later.
Nevertheless, the accommodation is super located. Very central. Clean. Quite big. Unfortunately, there is no stove to cook. But lovely welcome snacks, porto wine and the first coffee was secured.
The apartment is very noisy and the street quite early dense traffic, but with closed windows okay.
