I stayed in Miguel's lovely apartment by myself but there is more than enough space for 4 people. The host was very kind and helpful, providing me with great recommendations as soon as I arrived. All necessary amneties are in the flat and everything was working perfectly. I would only not stay here if I was searching for a really quiet place. But what's the point of Porto then?
The location of the flat is the most central one can be in Porto, with lots of cafes, bars, clubs and restaurants around. Public transportation and a supermarket are also very close. I loved staying here, and recommend it to anyone!
