We booked to stay for the OFFF 2015 festival which is hosted in BCN in May. Brilliant location literally 2 mins walk to the metro, Mercat Nou, on the red line (L1).
The apartment was very clean & quiet & is on the ground floor slightly below street level. Angeles was accommodating, prompt & always available on whatsapp or email with any queries we had. The only issue we had was the WiFi was difficult to connect to but I think the router just needed resetting. The apartment supplied 2 towels per person, but you'll need to bring your own beach towels & shower toiletries.
We headed into town for food so didn't use the kitchen, but there is a supermarket just down the road along with a bakery & chemist. We've stayed in Badal before which isn't far, so knew the area already. Its more residential than other areas further in but super easy to commute into central BCN.
First timers: I would recommend buying a Hola BCN travel card for the Metro as it works out cheaper than the T10! The metro runs til midnight sun-thurs, til 2am on fri and all night saturday.
Enjoy Barcelona, y muchas gracias por recibirnos, Angeles :)
