My husband and I can highly recommend Gilly's apartment, which is a separate granny flat in their backyard. It is cute and small, and beautifully decorated and fitted out. The shower takes a little bit to master but is worth the effort!
Gilly was flexible with our check-in and check-out, communicated really well and gave helpful directions. She also let us store our bags in her house after we checked out so we could go out sightseeing. :)
Cereal, milk, juices, tea and coffee are provided, and Gilly left a box of fresh fruit and baked goodies on our doorstep in the morning, which was just lovely!! There was a cute little courtyard out the front for our use with table and chairs and some pretty pot plants. We made good use of the wifi and TV as well.
The only issue might be the traffic noise on the other side of the very high courtyard wall, and the planes constantly flying overhead to Gatwick. However, I'm a light sleeper and had no issues!
Thanks Gilly!!
