I highly recommend staying at Eugenia and Karen's place if you are visiting Florence. The location is great, just a short walk less than 10 minutes from the SMN train station, and also close to a beautiful park and plenty of restaurants.
The apartment is beautiful, spacious, clean, and comfortable.
Even though the shower is very small, I found it to be one of the best feeling showers ever! Perfect water pressure!
The kitchen and outside patio are beautiful, the bed was comfortable, and all in all our stay was great!
