We had a great stay in Porto in apt. Valentina. We felt really welcome, there was some fruit, coffee and toast, pleased because of our late arrival.
The appartment is clean, spacy, has a great bed and is well equiped. It is well located near to the city, metro station etc. Eat pizza at Mamma Mia's!
António was a great host, really easy to get in contact with and willing to answer all your questions. We would recommend this place.
