Everything went just as expected, Elena and her husband were great! Would recommend this place to anyone visiting Florence - location was also perfect, 10-15min walk to all the main attractions and only 5-10min walk to the train station.
Tends to get hot upstairs (even at night) if really sunny that day (up to 37 degrees Celsius during our stay) and the AC doesn't really help because the cold air doesn't get there. However, there was a fan which made it fine for me! Moreover, we also had sheets for the sofa bed downstairs just in case we needed to sleep there with the AC on. Also received a map and suggestions when we got there - again, we had a great stay thanks to Elena and her husband and would recommend this place to anyone.
