The place is in a very safe area. Nearby metro is El Clot. It is 5 mins walk from the aprtment. Takes you to different places of Barcelona directly or to connecting stations to reach the heart of Barcelona - Gracia, Gothic quaters, Plaza catalunya, Sagrada Familia, Park Guell etc. Very easy and smooth transportation.
Also from El Clot metro you can directly go to airport. ( 30 mins ride). There are nearby groceries. And there are lots of restarurants as you step out of the apartment and are opened till mid- nights. We ate near the El Clot metro staion called "El Clot". Amazaing restaurant, great delicious food and not pricey. Lots of people eating till 12 am
The owner of the apartment is responsive and helpoed us with early check in too ( of course you have to let them know before) and the place is very comfortable and squeaky clean. There are lots of cutlerys, a big fridge and a microwave. The Ac runs very well.
I would stay there again if I visit Barcelona again.
