Silvia had communicated early on that she could provide us an early check-in at 10 AM (I had confirmed with her a few days before the trip and a second time the day before I reached Florence). However, when we went at 10 AM, we were told that check-in time was later and the room would not be ready before 11:30. She however helped us leave our luggage with her until we could get the room.
The room was in a great location - less than 10 min walk from the Train Station and a similar distance from the Duomo. It helped that there were multiple restaurants / cafes / supermarkets in the vicinity. Silvia also provided great tips about where to eat and what to see in Florence.
The room itself was well decorated but slightly small for 2 people, especially if you have a lot of luggage. We stayed in the room only to sleep / shower so it wasn't much of a problem.
Overall, enjoyed our stay at Silvia's place.
