Darren and Ralph's place is fantastic. Great location in trendy Surry Hills - many brilliant bars and restaurants just minutes away. Darren and Ralph are also great- they gave us very good recommendations and were very friendly and responsive.
The room and ensuite are very clean and comfortable, with several nice touches (e.g. beach towels provided). There is no door to the room (it's in the attic and open to the staircase and downstairs living area) but this was not a problem for us at all, especially for a few days.
All in all, a fantastic stay!
