Nice appartement in Bairro Alto, extremely clean. You will find everything you need to cook and relax, the washing machine is very convenient in summer and you can use the small yard to dry your clothes. The street can be a little noisy at night, so if someone is sleeping in the living-room, you might need earplug (i was there during World Cup so i dont think it's necessary all year!). But the room is quiet. Good bar and restaurant in the street and around.
Pedro was very gentle and kindly welcomes us past midnight... You can find all the informations you need to visit the city, including maps, in the flat.
We really spent a pleasant time in Lisbon! I would come back there without hesitation!
