We stayed in Jakub's flat in early January and is was fantastic and full of light. Check in was very simple and easy. The location is wonderful and close to the Old Street Underground Station though we usually took the bus from just across New N Road that takes you to the Old Street line or other lines south if you stay on the bus. Very convenient.
The flat: it seems on the large size for central London with two bedroom (one bigger than the other), a bathroom, a large space with the kitchen and living room with a TV. The deck was nice, too, though a bit cold in the Winter. The Kitchen had all the pots, pans, coffee/espresso makers, utensils, and tools that we needed and grocery stores a short walk away. There is a nice couch, TV, and internet for relaxing after a long day walking around London. The flat's temperature was perfect and there were good directions if we needed to change it. There was a useful instructions and suggestions provided in the flat. The flat is on the 5th floor and there is a lift in the building that works great. They even have lovely neighbors that we talked with a few times.
This was one of the best AirBnB places that we have had the chance to stay in. Highly Recommended.
We would certainly want to stay there again on future visits to London so I hope that Jakub goes on holiday more;
