The apartment is perfect. Very nice designed with a lot of a sun in the main room and it feels bigger and better than on photos. Also, there is a big private patio beside the apartment with wooden outdoor table and chairs that pretty nice to spent some time there. It's very close to the bridge with the best view in the city, so you easily can watch every day the best sunsets in the world.
The service is awesome too — you will get everything what you need or what you want. Estefania is a superb host, she is very kindly and easy to talk, always online and looking forward to helping with any question even if it’s not about the apartment.
The only one thing that can be uneasy — it’s too noisy on the nights. A lot of dogs in the neighborhood make some concerts every night. Also, both bedrooms are very close to the road, they are on the zero floor with thin walls, so you can be disturbed by a car or by a stranger, rarely, of course.
By the way, we had an amazing stay in Porto (3 weeks with a kid) and strongly recommend Estefania. She is a very pleasant and professional host.
