You will love this appartment and the host, Andre, is so good with helpful information and communicates with Whatsapp within minutes. The check-in was very easy. Andre has a touchpad outside that allows you access to the building and then he lets you know where to find the appartment key. Even has 2 sets of keys in case you need to go separate ways. Easy 5 minute walk from the Trinidade station and central location to all the historical sites in Porto. Leave yourself a half day to ride the old historical tram (Infante line 1) to Foz do Duoro, where the Duoro River empties into the Atlantic Ocean. The walk from the lighthouse to the Castle over-looking the beaches is wonderful. Because we stayed a week, we were able to make 2 day-trips by train: Aveiro (Venice of Portugal) and Guimarães (historical medieval city with hilltop castle).
