This place is a great choice, the tube is on the same block a min away from the apartment. Super easy to get to. Serena is very helpful and is very attentive and will respond to you very quickly. The Bed is super, super, super confortable.
I have sleeping issues and I slept like a baby. I recommend this place to anyone traveling solo and need quick access to the tube. Also you can walk along the bank from her place and no need to cross the street.
