When I was in Barcelona last week I stayed in an apartment close to the Las Ramblas, economic and nice. It was the perfect location to live.
I had the city center directly in front of my door and it was really easy to get access to the several ways of public transport.
I booked this apartment at www.barcelonapoint.com, and the service was really good and the booking process easy and quick.
I had an awesome week in this great city.
I can recommend everyone to spend their holidays in Barcelona.
