We didn't meet Isabel, but she was extremely helpful and communicative, with quick replies to messages. She was also very flexible about checking out. The studio was clean and although small, it has everything you need in it. Clean bathroom with nice and fluffy towels. With the balcony doors open, you can sit with a wine and watch people go by, with the doors closed you keep most of the traffic noise out to get a good night's sleep. To be fair, there is quite a lot of traffic here. But you have all of Porto close by, the old town and the river to your right, and lots of restaurants and bars to your left. Isabel has plenty of suggestions. Right outside, just a few metres away, is a nice cafe that serves breakfast all day.
