The good:
Excellent location, within 30 seconds walk of Diocletian's Palace Basements, the "Riva" and many cafes and restaurants. 5 minutes walk from the ferry and bus terminals. Right in the heart of the 'old town'.
Very friendly owner/operator
Very reasonable rates
Linen provided
Very clean

The not-so-good:
Up 3 flights of stairs to the 'reception' area, then one or two more depending on which room you're in. The stairs to the top floor dorm are particularly precarious.
Linen = bottom sheet, pillowcase and blanket - not so practical for the height of summer.
No airconditioning in 2/3 rooms. The top floor room is airconditioned but does pretty much nothing until the sun goes down.
Terrace is accessible only through the top floor room - can be a bit uncomfortable.
Rooms are very small and hot, especially when filled to capacity.

Overall, would probably stay there again, but not in Summer!! more
