Daniel's place is close to King's Cross station. There are a few streets that have an incline if you choose to get there walking. His place has "character" as it is kept in its original condition therefore it may seem old and dirty but Daniel assured us everything was clean (you can draw your own conclussions).
Do keep in mind that the tub is extraordinarily high and may be difficult for some people to climb up into it. The people we shared the bathroom with were nice and we took turns using the shared spaces. Though we didn't get a chance to meet Daniel, he answered all our questions and gave us detailed instructions.
