I want to thank Carlos for everything!
I really loved my days in Porto and he helped me to understand where to go and what to do to appreciate the City at all.
He is a very good host: he spent a lot of time with me explaining his town and understanding what I was looking for. His home is close to the city centre, to Sao Bento train station and - last but not least- very clean. The apartment is exactly what you could see in pictures.
I think I'll returne in Porto and I hope I'll find a place at Carlos'!!!
