I stayed with Sofia for 4 nights at the end of May 2019. She is great at responding to What's App texts. She was not available when I arrived in the middle of the day but I was able to pick up the key from the security/reception desk. Her apt in on the first floor of one of the buildings. It is very safe and secure and in a good area (very close to Navigli area and the metro at Porta Genova). The room is clean with lots of closets space and comfortable to sleep. Linen and towels were provided as well as breakfast (cereal, pastries, yogurt, fruit, coffee). The bed is big enough for two adults. The location was very good as it's a very close walk to the metro as well as trams to bring you into city center or further north. It's also within a 10-15 min walk of the popular/trendy Navigli area. Highlights of the visit were visiting the Duomo and the QC Terme day spa--probably one of the best spas I ever been to!! If you can, definitely spend a whole or half day at the spa (preferably during daytime weekday when there is less people). it's about a 15 minute easy tram ride away. On Sundays most of the Tabacchi shops outside of city center were closed so it took forever to buy a metro ticket at the machine underground. You can buy a 24 hour or 48 hour ticket to travel within the city. It is easy to get to her place from the airport--just hop on the Malpensa Express (13 euros) to Cardona Station and take the M2 line to Porta Genova (about 5-10 min, depending on time of day). It took about 60-90 minutes for this transfer as the Malpensa Express only runs 2x every hour. Sofia was very lovely and responsive to anything I needed. I highly recommend staying with her!
