My family and I had an amazing stay at Marco's appartement. He welcomed us with a bottle of Porto, explained us how the city works and indicated us where the good restaurants are. Marco is a very nice host, helpful and easy to communicate with. The appartement in itself was perfect : clean, in a quiet street and with everything we needed. The appartement was even bigger than I expected. I highly recommend this place if you come to Porto for a couple of days and want a cosy and quiet place to relax at the end of the day.
