Great located directly to Atocha station. It takes only 30min from the airport to the hostel with the "airport bus". It costs only 5€ each person and the bus stop is directly to the BnB. The City center is reachable by a walk. (1,5km-2,3km). The BnB was nice and clean. Only a little bit noisy because of the street. But it was no problem for us. If you're searching for a nice, clean and central BnB for a city trip you should check-in here.
