Had a lovely stay in Andrei's flat. It is smaller than it seems on the photos but with only three it wasn't crowded. The beds are very comfortable though the rooms can get a bit hot. Very clean with all the basics, and a bit more, provided I would recommend. It's very close to the Poble Sec metro and about a 20 minute walk into the centre. Speedy and easy communication with the hosts and the cleaning lady at the end of our stay. One thing to bear in mind was that it is on the 6th level of the building with no lift and only narrow stairs -- not a problem for three early twenties but might be more difficult for a family. Thanks Andrei!
