Honestly, we would not recommend Luigi's apartment. The apartment and location is really great but when we had a problem Luigi was very unprofessional and rude in how he treated us.
We spoke to Micheal and he said it would be okay to leave our bags in the apartment after check out for two hours.
On our last day when we went back to the apartment to get our bags the door to the apartment would not open. We tried for 30 minutes to open it with our key. Luigi sent a neighbor to help us and the man kicked and banged on the door for 10 minutes and was finally able to open it. Because of this whole experience we missed our train to Rome and had to pay 86 euros for new tickets. We were looking to see if we could come to an agreement on some sort of refund because we missed our train because we got locked out.
When we communicated to Luigi, he was very rude, didn't take any responsibility and completely shifted the blame to us.
He was not looking in any way to to understand or help us or at least just be polite. He said we could not have left our bags there, we would have to pay more and that it was our fault that we got locked out.
It was an awful experience.
Make sure to have anything you communicate with Michael in writing in a contract. I also hope they change the locks before a new guest comes and could have the same problem.
