I stayed here for 6 days and had a very nice stay. Dino is a nice host. He is very helpful and does more that you would expect to give you a pleasant experience, like bringing bread from the nearby shop and doing the dishes for you.
The room is small, but it works fine. It is a wonderful thing to wake up in the morning to a view over Regent Park.
The area seems quiet, yet only few minutes from 3 tube stations and there's a bus stop right around the corner. And the room is at the top of the buiding, so it is very quiet.
As I wrote, it's a small room, but so is the price. if you are looking for priceworthy place to stay, Dino's is very recommendable.
