Mario's place is a very cosy, refurbished apartment, with all you could need for an Edinburgh visit. The bed and sofa bed are very comfortable and even though you're overlooking the street, there isn't much street noise coming through.
The location is good, with a bus stop right in front that takes you to the centre in 15 mins, a big supermarket just around the corner, and a short walk from the beautiful Holyrood Park.
