Maria's apartment was as-described and listed, a basic 2BR (note the second bedroom requires passing through the first). Maria's responses were quick and for check-in someone met / waited for us at the apartment.
Unfortunately there was a water leak in a nearby apartment on the floor, which caused flooding into the main bedroom. This was a bit of a surprise-- fortunately only a centimeter or so-- Maria graciously offered to pay for a BNB downtown, but we had already unpacked and bailed much of the water with towels, so it seemed unnecessary.
I suspect the above will not affect other travellers, and we enjoyed our stay in Messina nonetheless-- Maria's hospitality and help through the problem was quite appreciated after a somewhat harrowing host in Napoli.
