The location of the apartment is very good, located in the center of Milan, just around the corner from the Duomo. Parking is no problem in the parking garage, which is a 5-minute walk away. The apartment itself could do with some refurbishment here and there. There are large and small stains on the sofa. The entrance to the shower is very narrow with a passage I estimate about 40cm. There is some mold in the corners of the shower, but you will find it in many showers.
Check-in first went well with a digital key. You must first download an app on your phone that allows you to open the large iron gate at the time of arrival and then the apartment door. Works well but temporary and that was not clear to me. I had not received an extra email from the host explaining that you have to get a real key from the key box to enter because the code via the app only works temporarily. The e-mail with these instructions did not reach me, so I was standing in front of a closed iron gate at midnight after I came back from the restaurant. My bags were already in the apartment and I was outside and it seemed that I could not go in that evening. There was an emergency number that I could call where I was helped by a very nice lady, but unfortunately she could not open the electronic gate from a distance. I was lucky that after 15 minutes, a few other people were just going in who were able to open the gate with key for me so I could get in. The door to the room did open with the electronic key. The very nice lady could give me the code of the key box so that I just came in the next day with the key.
On the face of it, an electronic key is a good system when properly communicated, but if something goes wrong there is a chance that you will be left on the street until the next morning.
I can imagine that this could be a problem for people who are not so adept at the new technology. The people of Sweetinn themselves are very friendly, understanding and helpful, but if you're standing in front of a closed gate at night, it's not much use.
Nevertheless, if you are looking for a location in the center of Milan, this is a nice location provided the price is not too high, but for the price I paid, the price quality is good.
