When we arrived there was a small chalkboard with a greeting for me, which was a nice touch. We had arrived a little bit later than expected due to bad luck with public transport but the person handling keys and so on (Barbara, a lovely woman) was very understanding and patient, which was nice.
The flat was as described, although there was no duvet cover on the upstairs bed even though we'd given the host no indication that we'd be sharing a bed (I'm male, my friend female, it's a completely platonic friendship, I'd referred to her in my first message to the host as 'my friend'). Also we had some communication back and forth with Barbara about the shower, as the drain was more or less clogged. Nothing was done about it in the end.
The kitchen had everything you would need and there was a supermarket not far from the flat.
The flat uses the old three holed power sockets rather than the EU standard which we hadn't anticipated, so we had to get an adapter. A few of the lights didn't work. One couldn't be plugged in because the lamp needed the EU standard socket! So we weren't the only ones in need of some kind of adapter, it turned out.
All in all we really enjoyed our time in Milano but due to the little things described above we give it 4/5 stars.
