Wow, that is an old and gorgeous one!!
These old pianos usually need a lot of money to be restored ( to sound well) as fixing the broken key, strings and parts of the mechanism takes time and knowledge. However, as the wood is old also, and the pieces are not the same as they are produced nowadays, sometimes it is not rentable and possible to restore them.
But it all depends on the condition of the piano. :))
Yes, very expensive but such a shame to just dump it in the trash...the age, the history and the family significance of it...and sine one day I want to move to Spain...
I understand. I had one very old grand piano, but as it could not be fixed and I could not move it to my house, my parents just didn't have more space in their house so they gave it away.
