I finally figured out the overnight layover lockers at the Madrid bus station, and it cost me 4 hours
Last month I had a 9 hour layover in Madrid and spent almost 4 hours just trying to find a place to stash my bag for cheap, because the airport lockers wanted 12 euros and the bus station ones were hidden behind a cafe. The sign was a tiny sticker on a door near gate 14, and nobody at the info desk knew what I was asking about. Does anyone have a go-to trick for finding cheap bag storage in a city you don't know, or do you just eat the airport price?
