Definitely request a transfer from and to the airport, it was very convenient. Hugo picked us up and was very helpful with the check-in. He was very friendly and polite. He made our arrival in Porto so easy. Diana's place was wonderful, comfortable and anything we needed was provided. It is located away from the touristic area which we preferred. Beautiful views of the sunset from the balcony. All the locals that we met in the building were very friendly.
Dont' hesitate to say hello and speak to them ( even if you don't know any Portuguese). Having 2 bathrooms was very nice. The place is very clean. We highly recommend Diana's place. We really enjoyed our stay. Obrigada !!
