It was very cool to stay in the same flat Galileo used to live. You can see both an official city plaque and plaque on the door that confirms it. We were welcomed by one of Modestino's colleagues who was able to show us in to and how to use the A/C.
The bed was quite firm but sleepable, and the bathroom was cleaning. Kitchen had all the things we need even if we didn't cook. The only issue we had was the A/C but Modi was prepared to send a plumber as soon as we needed it. The only two things I'd reccomend adding is a lamp as the room lights are very bright and a little uncomfortable, and maybe a stand fan as well. Other than this, all was good.
Modi kindly gave us discount cards for three local restaraunts - we found these restaraunts to be much better than the 'tourist traps' in the centre. The Santo Spirito district itself is a lovely place to hang out, even if you are a 20 minute walk from the most major tourist attractions. Despite this, it was wonderful being able to walk back to a busting square with bars, trattorias andic live music. Modi is easily contactable and gives good local reccomendations.
