We as a young couple travelling to Barcelona for 4 days chose Kellys airbnb since it was situated right in the heart of the old town, next to La Rambla. The building itself was like you would expect quite old, but Kelly made it into a cozy little get away apartment with functional and chic furniture. The apartment had two separate bedrooms, each with an individual bathroom, although we were sharing the common area with two other traveller's, privacy was still maintained. The kitchen was fully equipped, a washing mashine was also included. Making breakfast was no problem at all.
We really enjoyed our stay at Kellys airbnb during our entire stay, but we're glad to have left on a Saturday morning going to the airport, since we lacked quite some sleep the night before, due to the loud noise of (drunk) night owls passing through the nearby bars and streets. So be prepared to the noise level, although I guess that this is the price you generally pay for a location centrally located in the old town of Barcelona. All in all, we would still recommend staying here. Thanks again for hosting us Kelly!
