Great location. Local restaurants up the hill, restaurants down the hill. Nightlife and historic sites are all around. Be prepared to hike cobblestone hills in Lisbon and Porto.
The Airbnb is spacious with good amenities. There is a book of instructions and places to visit. This was extremely valuable.
Washer/dryer instructions are in the book which is important if you don't read Portuguese.
The unit has two balconies, great sunlight but also blackout shades.
