You could do no better than this!
Firstly Alexandre is the perfect host meeting with you on arrival, assisting with luggage and also providing valuable information regarding Oporto.
Secondly, the flat is extremely well positioned - close to train station (both regional and MET), key tourist venues and highlights.
Lastly, the flat was clean, spacious and generally quiet ... We stayed on a festival weekend so there was a little late night noise. Best way to deal with the noise was to be part of it.
Thank you Alexandre and Oporto ... We miss you already!
