Me and my brother stayed at Carolines flat over the weekend. As our flight arrived early, she already welcomed us in the morning, before the normal check-in time. We dropped our bags and Caroline showed us the flat and explained how to use all technical devices. She also left a paper with all necessary information.
The next Underground station is very close, so that we could reach all sights and attractions within minutes. There is also a Tesco market, right next to the building and a great view at the Arsenal Stadium. The flat was very clean and everything we needed (dishes, bed linen, ...) was there to find.
All in all we had a wonderful stay at Carolines flat and we would definitely recommend everyone to stay here, when in London.
