Marco's apartment is one of the best apartments we've stayed in. The space is big, extremely clean, with an astute attention to detail. The terrace is very nice, a great place to drink tea or coffee in the morning.
The apartment is located 15 minutes away (via the metro) from Firenze's train station, and has an assortment of excellent cafés and restaurants in the area. Marco's tips for where to eat were perfect - we highly suggest taking his word!
All in all, a great apartment with a great host!
