Lets play:

what's wrong with this picture?

1) Wellcome-> should be welcome-with one 'L'. Not sure where we are going with 'WELLCOME'

2) Wellcome to second floor...wait...isn't there supposed to be 'the' in this sentence?

And the fact that you have to be enticed up to 'second floor' sends up a red flag. what's wrong with the first floor??

3) 24 hours service-first, its '24 hour'-without the 's' and second, 24 hours of what exactly?

The funny thing is, I think this actually a legit place...and not a 'special' massage parlor. Its in a very 'chic' part of town which means they need to work on the sign-just a little bit.
