Apart from the apartment is just perfectly located, nice furnished, well cleaned and easy to find, it was Pedro by himself what was making for us the stay in Lisbon so amazing. He was helping us in every way and took perfectly care of us.
Trust him and listen to his suggestions and recommendations, you won't regret it.
He is a very charming and pleasant person, we got along very well from the first second.
So there is no more to say than go and visit Pedro in Lisbon :)
