Silvina is a wonderful host -- she's quick to respond and offered some amazing tips in her online guidebook. Marco met us and gave us some really helpful local tips including the best restaurant we ate at in Florence and it's really close by (I-Raddi). The location is not in the middle of the action but that was ideal for us -- away from all the crowds, quiet, but close enough with many local restaurants and within walking distance of the main sites. There are three flights of narrow-ish stairs on the way up to the apartment -- good to know if you have lots of luggage (we didn't). We walked to the apartment from the train station easily. The air conditioning was a fantastic perk in the heat of the summer!
