Just a small warning: the pictures are misleading and there is no heating (it does say "not included" but it's strategically put at the bottom). That is understandable during the summer but not at 4°C at night, in the middle of LONDON. Being beneath street level did not help the situation. During the mornings, it was warmer outside than in the room. The bathroom is dirtier and in a bit worse shape than presented. There is no hairdryer so no way any of the girls could wash their hair (that "is included", also understandable if someone broke it right before we arrived, but you can never know that), the microwave did not work at all, and no, it was not because the electrical appliance was turned off.
It was really close to the bus station and metro station and lots of cafes and shops nearby.
The house did not creak so there was no risk of bothering people after the 10 pm curfew if you went to use the toilet or get some water in the kitchen.
All in all, we would come back during the summer but any other season would be signing up for a cold (which we all now have sadly).
