My mom, my best-friend and I spent a total of three nights at the Hotel Sanpi. We had the junior suite and we loved it. It was very quaint and we got an amazing sleep! The room was pitch black at night with the shades and curtains and the area was very quiet. We accidentally slept until 11:30 in the morning! Something we never do... But obviously we needed the sleep.
I thought our room was a good size. We had three twin beds which was completely fine with us (plus a couch!) and we never felt crowded or like we needed more space. We also had a good size bathroom with double sink and a jacuzzi bath. They also delivered a fruit basket to our room.
The breakfast was pretty good at this hotel also! It was a buffet with yogurt, fruit, eggs, croissants, etc. The staff will also give you a cappuccino or tea if you ask. We were so sad because we only got to sit down and eat it once because we were either leaving too early or we slept in.
The staff was very friendly, personable and helpful. The staff gave us a map of the city with places to go and see. I did research beforehand and had a good idea of where I wanted to go see in Milan. For example, we took a day trip to Lake Como and Bellagio. It was so beautiful.
We LOVED LOVED LOVED the restaurant we visited across the street, the Il Carpaccio. We went there once for dessert and another time for dinner. We fell in love with the people who ran this restaurant, they were so sweet and funny and were taking pictures with us and giving us shots of limoncello. They had amazing homemade desserts like cheesecake and tiramisu. Everything was reasonably priced too.
We took the train to/from the airport and walked to our hotel from there. It's a very easy commute and I believe it was only 12 euro per person each way. Much cheaper than a taxi! We also walked to all of the landmarks from our hotel. It may be a good distance for some, but if you don't mind walking you'll be fine.
Our only complaint was the neighborhood. As you may have read in the other reviews, there were a lot of minorities in the area as well as graffiti. However, it was only for a few blocks of an iffy neighborhood. I'm sure the area isn't that bad though because no one actually bothered us and we were three women traveling alone.
