We can totally recommenend this appartment, located at the old city part of Porto. It feels like a tiny house and is very romantic! From there its an easy walk through town and to all touristic spots. The staff is very helpful and organized the airport transfer for us. Just to let you know: Key pickup is at different pickup points in town, for checkout you can leave the keys in the appartment, which makes it easier ;) We can also recommend a free walking tour with the company „Porto Walkers“!
