Marta is a very nice host and instantly replies to any forms of contact. The place is literally at the doorstep of Corvetto metro station (~20m) so although it's not right in the city it is very covenient to get to the duomo and other attractions! The apartment is on the 7th floor but there is an elevator, with a nice pastry shop right downstairs just to the left. Just be abit careful with the shower as there is no curtains and so it is easy to splash/spill onto the bathroom floor.
