Renato was by far the best host we have had.
The apartment is wonderful. Great bathroom and shower, fantastic location only about a 4 minute walk to the metro which links directly to the airport.
You do have to walk up a couple flights of stairs which wasn't a problem for us. The hills of Porto are a bigger challenge :-)
The only minor problem is noise from the street on certain nights. We arrived on a Tuesday and it was super quiet all night. Wednesday we heard partying outside all
night.
Bring some ear plugs just in case. I don't think you will find a better host or Apartment!
