My sister & I stayed Marella's apt for 3 nights in Sept and used self check-in which was easy and went smoothly. The apt is exactly as pictured and described. A great location - right of Piazza di Santa Croce. We found it quiet and enough space for 2 people. One small flight of stairs up to the apt - very manageable. One piece of advice, the shower is new and clean but just has a small "lip" or edge so be careful to not overflow. We found that not turning it on the highest water pressure or turning it off a few seconds to let it drain while showering did the trick. Great stay! Also - we found taxis in general are hard to come by in Florence. We walked almost everywhere but the few times we needed one you have to go to a dedicated taxi stand (there is one off Piazza Santa Croce) but I suggest booking in advance if you know you will need one - there is a number you can text to do so.
