Looking for piano to play on (Florence)

Hi -- I'm a physicist in my 40s, coming to Florence soon to stay for 6 weeks and work at the Galileo Institute on Arcetri Hill. I'm a pianist, too, and won't have a piano in my Florence apartment... so I'm interested to try to find someone who has a piano who might be willing to have me play on it a couple of times a week. Glad to pay to have it tuned if that's helpful.
