Although we did not have a chance to meet Helder, we were met and communicated with Miguel throughout our stay in Porto. He was at the apartment upon our arrival and was gracious and helpful, providing maps and suggestions for restaurants and tours. The apartment was not only beautiful, it had all of the amenities we could need for a comfortable stay, including extra touches like some food in the refrigerator and a bottle of local wine! We only wish we would have stayed longer, and will do so in the future. Thanks again Miguel!!
