Everything was very easy, I booked only a couple of days beforehand and it was very smooth. The apartment is gorgeous and exactly like the pictures, the bed is comfortable and everything is new! Check in was easy, and I got some very handy hints about what to do and what to see. Would definitely stay again. The only thing I noted was that there was no fan or AC, or windows to open - it wasn't very hot when I was there but still slept with the back door open one of the nights. It seemed like a safe neighbourhood but it made me nervous sleeping with the back door open on a ground floor apartment. But the terrace was a perfect little oasis in the middle of Porto :)
