Ruiz is a really great host who sent us good information about Porto and responded promptly to our questions.
The apartment is both stylish and comfortable and very well positioned to walk down into Porto and explore the city. We loved it.
Porto itself is great with a good supply of Uber cabs to get you back up the hill after a long day ding tourist stuff. The seafood is great, if occasionally expensive. Do check out the port wine cellars on the other side of the river and walk over the big bridge at both levels. The view from the higher level is phenomenal.
