We were 2 couples travelling in Milan, and we had not a very good experience with Elena’s flat.
The Flat is certainly well situated (5 min walk from the Navigli and 15 min from the Duomo) which is quite practical, but it is also on the 4th floor without elevator, which is more complicated when you have luggage.
The flat is spacious and clean, but there is only one bathroom and one WC (on the main floor) , when both double room are on the mezzanine floor (yes one more floor…) with only one bedroom with a double bed. So overall, the place is definitely not meant for 2 couple.
But the most disappointing was certainly the behaviour of our host, clearly Elena took the opportunity of the Expo to rent her flat as much as she could, with guest coming every days. Consequently, we were ask to check out at 10 AM sharp, with no flexibility at all, Elena called us several time (even a t 9.00am on Sunday) to make it very clear, and indeed at 10 AM on Sunday the cleaner was here to kick us out. In such a rush, my friend forgot her toilet kit, the cleaner did not even dare letting us know and put everything in the garbage. So to sum up, I would recommend the flat only if you are heavy hiker and early riser otherwise walk away.
