We just stayed one night at this hotel and everything was perfect.
The room was spacious,and clean and offered everything we needed: tea/coffee, free minibar, wifi, slippers, toiletries and even chocolate with a nice little welcome message. The decor was beautiful.
The staff was amazingly welcoming and professional - not just one person, but ALL of them - this really made the stay something special.
The breakfast was very nice - varied and fresh. Quick service.
The location is great - right in the middle of everything, yet nice and quiet. There are restaurants close to the hotel, but most are rather touristy, so we went to the Brera-area close by.
I cannot recommend this hotel enough - it deserves another star because of the high quality and service.
