I stayed at UNA Maison last November 2011 for a few nights and it was a fantastic decision. I cannot stress enough how good the location was being just across the street from the Duomo!
Also, the room was very spacious and my oh my the bathroom! Super clean, super hotel.
It is a bit pricey but at the same time it was worth it. Only recommendation would be for them to include breakfast in their pricing but anyway when in Milan who really wants to just stay in the room!?

After our terrible experience at G Boutique Hotel we were fortunate to end our trip to Italy at this little gem of a hotel. I can't rave highly enough about the staff and how very helpful they were. On our last afternoon I asked if they had champagne glasses. They did so I asked if we could have two. A few minutes later they arrived with 2 glasses of champagne. I explained that we only wanted the glasses. The gal laughed and said she misunderstood but now the champagne was on them. That said, our suite (we were surprised) was great...lots of room, and the location could not have been better. This is the place to stay when in Milan.

This place is truly the best in town, amazing location, extremely clean rooms, incredible staff, never seen hotel staff as eager helpful as in UNA Maison.

trust me, this place will make you love Milan more, strongly Recommend

Stayed for one evening. The location was perfect!..The hotel staff was unbelievable!. Francesco even accompanied me to the traín station to help me with three suitcases i couldnt carro by myself, even waited for the traín to arrive to help me load them aboard. I could not believe it!. The rooms are nicely decorated and comfortable!..Will most definitely recommend...
