This house is perfect for groups who want to have a real feel of Lisbon while still having a great place to rest and socialize - the social space is great, and the bedrooms and the kitchen are good. The location is hard to beat - it's one of the most lively and interesting old neigbourhoods in Lisbon - with the subway within a 5 minute walk and the Cais do Sodré train station (access to the great beaches near Lisbon) only a 10 minute walk, always going down. You'll love it if you come to Lisbon in the Summer.
The price is great value, especially since it can accommodate 10-12 people easily. More than that might require some tweaking. Overall, a great experience, and one I'd highly recommend.
