Luis place is great for short trips. It is fairly central, Kings Cross is only a ten minute walk away.
The neighbourhood is really quite and secure.
Our room was clean and big enough, the only issue was, that we could hear train noise, but for me personally it wasn’t a problem. Tea and coffee was provided in our room, as well as water.
The bathroom was just down the hall and for the whole house there are about three bathrooms, which definitely was fine. Everything seemed clean and good equipped.
I would definitely recommend this place and would come back.
