We are getting married in Madrid in September, and need help from someone!!

we are staying at the Hostal Residencia Don Diego in the Salamanca-district (Velázquez, 45), do anyone know

1. A hairdresser in the area??
2. A florist in the area??

We are arriving Madrid the evening before, so I'm afraid we don't have too much time to search the area for these things. I prefer to order some days before.....
