The large room was very nicely decorated with plenty of shelf and cabinet space, plus a desk and chair. It has a very nice, open, bright kitchen if you need it. It is owner occupied with only two rooms being rented.
Nanilu is very friendly and helpful with directions and the best route to Heathrow. (The express trains are not needed from here.)
My only issue is that it is described as being in central London. This may be true from a Londoner's perspective, but it is well south of the main tourist attraction area. This is offset by the extensive and frequent public transportation system. This is true even late at night and on weekends. In fact, they add late night service on the weekends to please the tourists. So even though getting there requires both an underground route and a bus, there is very little waiting and getting from the tourist area to this location only takes 20-30 minutes.
Overall, I was pleased with this stay and would consider using it again.
