Sofia was really helpful with everything. She doesn’t speak English but she can manage everything with a translator. The hostel is well equiped, the beds and pillows are really comfortable. It 15 minutes walk from every main attractions, so it’s at a comvinient place. We had a smooth check in and out, we could leave or backpacks there and she even helped us to find the bus to the airport. Bring an earplug, as Madrid’s streets are noisy, but it’s the same everywhere. Thank you again!
