Wifi: good. Location: neutral, because it's close to Atocha station, but still somewhat far from metro stations and major sights. Staff: friendly. Safety: the main door is always closed but the in-room safe didn't work. Soundproofing: terrible--I could hear every single sound in the hostal despite being in the room at the end of the hallway. If the soundproofing were great, then I would have rated this 8.5/10.
