Pedro and Ana's place is right in the middle of the action of Bairro Alto. Praça Luis de Camoes is a short walk away. That's the heart of the neighborhood. Lots of amazing bars and restaurants in walking distance. The nightlife is fantastic.
As for the hosts and accommodations you will not have any complaints. The place is clean, comfortable and roomy. Ana catered to our very early flight in by allowing us to check in early which saved us from roaming the streets with our bags for hours. Can't recommend them enough.
