Marks place is really nice. It’s in a fantastic location and is very clean. I wouldn’t recommend for families though, it has some comprehensive house rules and it’s very difficult to keep children as quiet as Mark suggests especially on the timber floors. It also lacks basic things like coffee & tea, tissues and breakfasts foods.
Overall, however, it would be fantastic for singles or couples looking for a great weekend away in Sydney! It’s clean, quiet and in a fantastic location! Without children, I’d stay there again!
