Manuel was very friendly and helpful, even going so far as to pick us up from the airport (particularly good as our flight came in an hour late, after midnight). He gave us great tips on where to eat (Casa Guedes for the pernil and vinho verde and Venhem mais cinco for the killer prego and crazy gigantic chocolate cake - both within a 5min walk and really good) and places to visit.
Apartment was exactly what we needed - great location, lovely fresh modern and clean, comfortable bed and great shower! Everything we needed, including a coffee maker, and Manuel supplied coffee pods. Great way to start the day. (Though definitely also go for coffee, toasted breadrolls and a nata at Evaristo round the corner).
We just had such a lovely time in Porto, and Manuel's place was the perfect base.
