Sam's place (and Sam) are gems. My stay at Sam's was terrific. The location and proximity to the tube are the best I've had in mt visits to London.
My flight arrived quite a bit earlier than check in and yet there was no issue at all when it came to checking in early.
The room and ensuite were just the perfect size, and having a kitchen with a fridge, stove/oven and even a washing machine was a blessing. Little touches like small vases of flowers, toiletries available for use, and even coffee and peanut butter in the kitchen just added to the already comfortable atmosphere.
Sam herself is incredibly lovely! She is quite knowledgeable of the area and had great suggestions for things to see or do, even for a guest that had already been to many of the big landmarks. She is available if needed, and we chatted often when I was in the kitchen or common area. But she also gave me my privacy and space
Though I usually travel with a group that would be too large for Sam's, I would happily choose her place again on my own. I highly suggest her place (and already have to several friends).
