We had a wonderful time in Porto, and Luis' apartment was in the perfect location. Luis welcomed us, and gave really useful recommendations and tips for our stay. The apartment is spacious and has a good kitchen, with enough equipment for self catering. The street outside can be lively, but the noise stopped after 10:30 at the latest. The balcony was a highlight, great for having breakfast and watching the world go by. Luis kept in touch, making sure that we were alright. Thoroughly recommended!
