We had a perfect stay. The apartment is just as described if not better. We are a family of 4 and we had more than enough room with two bedrooms and two bathrooms.
The apartment is less than 5 minutes from the beach which was perfect. There are plenty of great restaurants right outside the apartment doors...you can literally choose to eat or drink whatever you want. We chose to take taxis instead of public transportation into the city a few times with no problems and lack of high costs.
The host was very helpful and responded quickly to all correspondence.
I highly recommend this apartment to anyone looking for a great stay in Barcelona that includes a little beach fun in their stay. We had a great experience.
