Juan's apartment is in a great location - 10 minute walk to the beach, less than 5 mins to the Marina L1 metro stop and 5 mins to Parc de la Ciutadella. The apartment is very clean and the room we stayed in was more than enough space for two people.
Juan is a great host as well, he provides a lot of information upon arrival and has a very accommodating check-in/check-out policy.
