My friend and I just returned from a long weekend in Porto. We thoroughly enjoyed the trip, partly because of where we stayed! Daniel is a very friendly and flexible host. The house / apartment is bright, clean and inviting. The bed is one of the most comfortable ones we've ever slept in (not so good when you only have a couple of days to explore this city :D). Everything you must see, whilst visiting the city, is only a walk away, yet the flat is situated on a quiet road, close to transport and grocery stores. I'd definitely recommend Daniel as a host, as well as his flat! Happy Travelling.
