We had just a great time in this beach flat in the mid of September. The Host was very welcome and responsive. Apartment had everything we ever needed. Location was so convenient with a lot of good restaurants and shops just down the street. We could walk to the beach just across. The beach was still full of people but clean and sea was still warm and clear. Nu provided two beach umbrellas that helped a lot. There also was a beach service for chairs and umbrellas right on the beach. It was a bus stop next to our building but we never have to use public transportation. We walked and took taxi. Taxi is very cheap in Barcelona - just 5-15 Euro to the main sightseeing (price per car and we had 3 adults); 30 Euro to Airport. There was app for smart phone that we used that worked just like Uber – it actually saved us a lot of energy and time. You also can catch taxi every there anytime on the street.
We loved Barcelona! It is a great place for people who still would love to swim in the sea and spent some time on the beach; but at the same time visit just amazing sights that the historical city can offer. Make sure to buy your tickets to Sagrada Familia and Park Guell online the day before. You will not be able to get in right away. Try to visit Sagrada Familia on the sunny day so as the colorful lightening through the windows inside the cathedral becomes just amazing!
