José's Apartment is great for a longer stay! It is so cozy, that you don't want to leave it, even though it is so centrally located to do many things!
However, you should keep two things in mind before booking. First, it doesn't have any daylight, as it is located in the ground floor in one of El Born's famous narrow streets. Second, that it is a old building and the door/windows are not very well isolated making it rather cold in fall/winter. The small electrical heater provided can compensate that a little bit.
José is incredibly nice and forthcoming, he responds super quick whenever I had any questions.
Overall, I would definitely recommend the place!!!
