I stayed at Jack's for some days for meetings in the city. He made sure everything was ready and kept in contact before and during my stay.
The room was great, clean, quiet, with a nice bed and close to Canal for runs. Also got to use the kitchen and fridge so managed some meals at home. Jack and Isobel were nice people and great hosts.
I would recommend this if you need somewhere to stay and want to be walking distance to East London/Old Street and others
