We had generally pleasant stay in Silvia's, with some minor pitfalls.
The location of the apartment was fantastic, minutes away from Milano Centrale railway station. The apartment was easy to find on google maps by foot.
Check-in was smooth, and staff from hostmate waited for us outside the apartment to bring us in. (we checked in after 6:30pm so we paid 20euros for late check-in and opt for checking in at the apartment)
When we first arrived the apartment, everything was neat and tidy at first, but we eventually realised that the floor was very dusty and was not cleaned properly. I feedback to Silva and she responded very quickly. I believe it was just a once-off event as the previous comments of her place was decent. She offered to get a cleaner in the next day to re-do the cleaning, but as there was all the cleaning equipment available in the store room, we decided to do it ourselves and Silvia waived our cleaning fees.
When booking Silvia's place via AirBNB we missed the fact that there was no air conditioner (although it was actually stated in the website, we didn't scroll down to look properly). We came during Summer season and it was very hot during the day. We usually spend most of the time outside and only return at night, so we didn't experience much issue with the heat without air conditioner. We manage to sleep decently with a standing fan that was in the apartment. The only issue with the lack of air conditioner was mosquitos. We kept the windows open most of the time and throughout the night to get better ventilation, thus the mosquitos from the garden flew in and we had a bites here and there. It wouldn't be a problem at all if we came in the winter.
Overall, Silvia's place is a nice and cosy apartment and we did have a pleasant stay there.
