We knew Barcelona already and loved the area of El Poble Nou, so the flat was perfectly located for us; in a quiet corner but just at 200m from La Rambla where restaurants, shops and people are. Not to mention you're at 5min from the beach - large and much quieter than The Barceloneta beach.
The flat has everything you need; from the AC, very well equiped kitchen, washing machine to the internet connection. It's not brand new, the beds are not so comfy and the photos are taken with a very wide angle... but it was perfect for us, our 9 years old daughter and our dog.
