We were a group of 4 girls and stayed in Daniel's apartment for a weekend. The apartment is lovely and there is a metro stop right outside the house, and a bus stop that takes you to the Barceloneta beach (it's too distant to walk there).
We loved the apartment, it was huge and very clean. Daniel was very helpful and kind. A friend of Daniel welcomed us in the house and she was very nice too.
We would definitely recommend this apartment!
