We stayed at Prince's Square for a week during summer. The location is great with easy access to Bayswater and Notting Hill Gate tube stations and plenty of restaurants and supermarkets. The apartment itself was very spacious with high ceilings in the living room. It has a nice terrace to enjoy although the floor was quite dirty and we found we were bringing dirt in to the apartment. The kitchen was fully equipped and had plenty of basic cooking items which was helpful. The master bedroom had a smaller balcony overlooking a neighbour's garden. A nice view from the bed itself but when you stepped outside, you saw a power station to the right and a neighbour's windows very close to the left. Guy and Emma were very easy and prompt in communicating. They gave clear instructions regarding the apartment and there was an information binder when we arrived. For us, there were two main issues. The first is the lock box. I read several other reviews saying similar things. Namely, that the lock box is located around 600m from the apartment and if you're by yourself and have luggage, it's not at all convenient. It's the only Airbnb that I've stayed at that has had a lock box off premises and I don't think it's unreasonable for that to change. The second is the price. Guy was very kind to offer a discount (a very small one, but still appreciated) for the initial booking as it was last minute. But then we extended for two extra days and weren't offered a discount for a week's stay (which most listings, do). They also charged a second service charge. And despite the lovely spacious condition of the apartment, it is still only a one bedroom apartment and it was expensive per night.
