We stayed at Eva's place for three nights and found the location perfect for our needs. The airport bus, and Eva's directions were a stress buster, and the Metro was right there. Lots of great restaurants and bars close by, try Flax and Kale for sure. Walkable to Las Ramblas, La Boqueiria and many others. Take a Fat Tire bike tour! There are a lot of stairs to the flat so just keep that in mind... We found it to be great exercise :)
