In the end I didnt get it, they actually never got back to me and one day the offer ended.
I am not unhappy about that though, piano is a bit too noisy for my apartment, I wouldnt feel comfortable with everyone in the house listening, and than I would love to play at 3 a.m....
Right now I am eyeing on a very different rare musical instrument that needs a lot of maintanance and refurbishing, and I am not telling what it is right now,...as not to spoil the chance, anxiously wating for a reply to my offer.
