The location is great as described just few mins from the tube, and it’s very easy traveling to central london only 20 mins by tube. The room is quite small but it was fine for us as we spend most of the time outside the house.
Petra told all the household rules in advance, we respected it so there was no issue at all.
Petra surprised us with christmas card and chocolote on arrival. She also allowed us to use her kitchen on christmas day because most of the shops were closed and this was very helpful.
There was only one issue, the front door was a bit hard to unlock but Petra was very responsive on phone and helped us.
In general, we enjoyed our stay at Petra's house and if we visit london in the future we will do it again.
