Nuno is very friendly and the communication was excellent for the whole stay.
The apartment is very spacious, clean and comfy. A nice comfy bed and small balcony looks out over street.
There is everything you need in the kitchen to make your own food, including toasty machine :)
The location was good for us, it's a little out of the main city buzz, but a short walk to the top of the main bridge.
We stayed two extra nights because we liked Porto and Nunos apartment so much. Definitely recommend. It was also the best price we found for a while apartment.
