We had an amazing 2 week stay in this perfect apartment in Gaia. The apartment is exactly as shown in the pictures - comfortable, modern, spacious and very clean.
Silvia and Ricardo were perfect hosts, they greeted us at the apartment and gave us all the information we needed as well as an enormous list of things to do and places to eat. They were very easy to contact and very responsive to any questions.
The location couldn't be better - the metro is 1 minute away or you can take a scenic walk over the bridge to get into Porto. There's supermarkets and shops nearby (as well as the best pastries ever at a pastelaria on the way to the bridge)
If you are planning a visit to Porto you will struggle to find better accommodation than here - it is fantastic!
