Hotels May 21-22
 

So I'm trying to book a hotel room in Madrid for the weekend of May 21 and 22, 2016 and everything (Ritz / Villa Magna) is sold out. Is there some event going on? Because it's over a month to then and it seems a little weird that it's sold out. Also prices from May 1 - May 19 and May 23 - May 30 are very low so I'm not understanding? I tried to google but couldn't get anything

I just checked those dates on Booking.com most rooms are reserved but there are still many available.

It's undoubtedly San Isidro, Madrid's big fiesta. Lots of bullfights and partying. Have fun !

Google San Isidro

Ritz available on booking.com
