Mariana did a fantastic job with communication and with our arrival. She provided a great overview of the home in person, and let us know where everything was in the city. Another huge bonus, it's an area that doesn't at all feel like a "tourist trap". You really feel like a local when you stay in this area. El Born and Gotic are great, but it's swarming with tourists which can take away from the charm a bit.
Another bonus, the apartment is a block away from Barcelona Moto which is a fantastic scooter rental place. If you feel you can brave the traffic, I would highly recommend seeing Barcelona on a scooter, it was such a highlight. Overall I cannot wait to go back to Barcelona and will stay here again if its available.
