The location was convenient in a nice part of town - just a few blocks from La Pedrera Casa Mila and high end shopping. Karla did give directions to get to the place, but do realize that her English is weak, so be understanding. The door to the building is between the XC Gelateria and a travel agency.
The group is very friendly and there is the occasional group bar crawl, which is nice [but I did not get to take advantage since is was the night before my departure]. The terrace is lovely.
Do realize that this is not a typical AirBnB listing and would be more suited for hostel world. The rooms are mixed gender and packed in with beds in what used to be a flat in an older historic style building.
There is only one bathroom [one toilet, one shower] for a dozen or more people to use. Do bring shower shoes do to such heavy use by so many people. I suggest bringing your own towel too, otherwise is will be mixed up with someone else's.
Bring your own pad lock if you want to lock up your personal valuables. Upper bunks have no outlet for charging your devices. There is a power strip on the floor for sharing within the room [ not enough for everyone].
If you are a light sleeper, I do not recommend, since others will be coming and going at all hours and you will hear the periodic rumble of the subway below; but the access to it is not for another couple of blocks.
But, if you are looking for a safe place that is cheap - this is it.
