This is an absolutely lovely and beautifully designed loft, which takes great advantage of the antique space and painted ceiling to create a unique atmosphere. We very much enjoyed staying here. The location is also great, only a block away from Piazza Sta Croce. The apartment is situated on the ground floor in the inner courtyard of an old palazzo - it's quiet and serene inside and out, despite the busy and noisy activity on the street outside. In the mornings the sun comes in and the space is bright and cheerful, and in the afternoons it's shady and cool and the AC works really well -- it was terribly hot during our stay so that was a important. We hope to return sometime!
Positive points: Ground floor location: it's really nice after a long day not to have to deal with stairs to get home. Quiet inner courtyard, spacious marble bathroom, and most of all, the beauty of the room.
Downsides: It's a loft, so it's all one room: you won't have any privacy from each other. Not really a problem if you know to expect that. Also, the space has been well used and some aspects of it are a bit funky.
