Luis is definitely a superhost. He gave a wonderful introduction to Porto and had a lot of great tips. I would give 5 stars, but my friend and I are non smokers and even though the building says no smoking I woke up many times in the night coughing. Maybe this is typical in all of Porto though. We also weren't aware we would be sharing a double bed. Other than that, the balcony views were spectacular and we felt a nice sense of the local culture.
