Welcome to my space!
It is in the very center of Barcelona, possibly the best location in the whole city. You can walk everywhere! The park is just around the corner and the beach is about 15 minutes away. And if you are more of a city visitor type, you can just take a stroll around the crooked little streets in the area. And if it's the nightlife that you crave, you have hundreds of options for bars around the neighborhood.
Hope you enjoy your stay!
