the ceiling in the shower is very low, and in addition it is plastered in a roughcast. So it was nearly unavoidable that while washing my hair, I scratched my knuckles on the plaster, which hurt a bit.
Half an hour later at breakfast, I observed my collegues knuckles where scratched similarly and he confirmed it was for the same reason. I guess if you are one of the taller people (we both are about 185cm), please be cautious taking a shower in order its leaving marks.
Gut: lovely people
Nicht so gut: always have at least one more experienced person
Lage: close to Birminghams business park, the only close thing to go to is the Birminghams NEC
