Pedro and Ana's place is superbly located in the heart of the happening Barrio Alto district. Plenty of bars and restaurants nearby (there was one across the street which had 0.5 L of beer for just 2 Euro!). Area is great for a night out on the town.
The space isn't the easiest to get to if you have lots of heavy luggage as there are quite a few narrow stairs but once you are inside it's perfect.
Their local guide to Lisbon really helped guide our time there - my favourite city in Portugal! Thanks Pedro and Ana!
