Tiny apartment. It’s ok for 2/3 days max but too crowded even for a couple I would say, there’s barely any space. A lot of stairs, no elevator. Also, bring your own hair dryer and toiletries.
The stairs going up to the gallery where we slept felt a bit unsafe. Location is good. Overall, it’s ok if you’re looking for a cheap stay in Milan only for a few days, but you definitely get what you pay for.
