Would definitely recommend.
Tiagos place is very lovely. Me and my friend visited Porto for a mini break and staying at a nice place certainly helped.
The flat itselfif very nice and clean and is stones throw from the beach. it is very convenient. there are many supermarkets and restaurants around the flat. Tiago had great communication and it was very easy for us to check in and out.
Next time we are in Porto we will definitely stay with Tiago again.
