We had a great time at this apartment, the plus is of course the location, so close to the train station and the Duomo, as well as all other attractions, we did everything by walking.
Things we liked: Andrea was a perfect host, he was waiting for us at the apartment and helped with our luggage, great communication before and during our stay. He did not mind that we come with our 4 year old, we were 4 adults already.
Apartment as described. Air conditioning worked perfectly, internet as well. We had enough place to put and hang our clothes. Andrea agreed to a later check out +2 hours since we had our train at midday.
Things that could annoy some people: noise from the street (many cars and noisy people walking by); small kitchen with no microwave, however we found everything else that we needed to have breakfast or dinner (pots, pans, etc); small shower but it did not bother us, we had very hot water :) the apartment is in the 4th floor with no elevator, so it's probably not for you if you are disabled or have a hard time with stairs.
We were very happy to stay at Andreas place! Thanks a lot!
We encourage you to eat at the Mercato Centrale which is near by and is excellent value for money.
