Very positive experience! We arrived pretty late at night (around 11) and still got the keys (we did not actually meet massimiliano but got the keys through the groundskeeper Francesco). The appartement is very small (max 3p!) but contains literally everything you need (from bottles of water to a washing machine and even a hair dryer!). Best thing about the loft is the location: at the heart of the Navigli area with lots of cafes and restaurants!
