I'm going to be in Madrid for a short time and haven't been before so am looking for some tips on best part of town to stay, any 'must sees' etc. I'm arriving after 9pm on a Thursday and leaving Saturday morning. Basically looking for somewhere nice but not too expensive if paying cash. I also have Points with pretty much every hotel programme and am happy to use them if there's a standout redemption though. I'd prefer to be somewhere near lots of good tapas bars etc, but won't be having a really late night. Cheers!
