I have stayed at about 30 airbnb's and Noemi is among a handful of outstanding hosts in the last 8 years! She is communicative and really seeks to support her guests, but she is also not invasive.
The house is located in an ideal location just over a block from the Arc de Triumf. We were able to walk to the Gothic area, the Ramblas, the beach - perfect (and I am 71!)
The room is extremely small (8ft by 10 ft), with an also tiny bathroom, and one window; but fine if just for sleeping. If you plan to go in the summer, I would be very sure that NOemi has a working, portable airconditioner. Also, if you need internet access, be sure she has gotten a signal booster or ethernet cable. But if you are looking for a friendly place to rest between BArcelona jaunts, this is perfect.
