Most importantly for us, Carolina's apartment was sparkling clean and well furnished. Her assistant, Alberto, expertly walked us through the check in process and patiently answered all of our questions to our satisfaction. The apartment is situated one floor up on a quiet pedestrian way between two fairly active cross streets (one of which, Carrer de la Princesa, sports a couple of nice hotels, which results in a flow of taxis, if one is needed). So you have the buzzy nightlife of the El Born district just steps from your door in any direction. Or if you need a break from the action, you have the relative calm (remember, you're in an urban setting) of your apartment on the vehicle-free passage way. Carolina remained available electronically throughout our stay to answer questions, etc. This was definitely among the best Airbnb experiences we have had, and I would recommend it, with gusto, to anyone who should ask.
