We stayed at this apartment for 2 months and we had a great time! The apartment is not huge but for two people it is a perfectly comfortable and cozy home. It is equipped with everything essential and has more storage space for clothes and suitcases than one might expect from the pictures.
The location is unbeatable: close to the metro station, many supermarkets and restaurants, and the beach of course. Barceloneta can sometimes be a bit noisy at night but there is not much going on in this little side street.
The hosts were super friendly and made sure we had everything we needed. They responded to messages immediately and helped us when he had questions or problems, e.g. by exchanging the ceiling light bulbs.
We can definitely recommend this apartment, especially for couples. If you're looking for a functional, cozy apartment with friendly and reliable hosts, both close to the beach and the town's heart, you have found it! :-)
