It's all about location, location, location. The apartment lying between Santa Maria Novella and e.g. Palazzo Strozzi is therefore nicely located. I frequented the Irish Pub around the corner quite a few times. But the area is, as the whole 'Centro Storico', overcrowded and that made me, as it already was in my planning, travel to places outside of Firenze.
The apartment is good, kitchen and bathroom are sufficiently equipped, the room is nicely furnished. The host Alessandro is a nice guy, although I met him only 10 minutes at the check-in. Overall the place is value for money.
