We (family of 5) stayed 2 weeks and very much enjoyed the time. Sergio is a great host and can help with tons of useful information. He was very quick in answering all our questions.
The house is nice, tidy and clean. Sergio even sent a cleaning lady in the middle of our stay and all beds and towels were changed.
The house is located approx. 8km south of Porto. The sea and beach are in very near walking distance and you can easily commute to Porto city center by train within 20 minutes.
Thanks for the great vacation!
