Even though my sister and me decided to visit London very spontaniously, like 2 or 3 days before, everything worked perfectly well. We had a very nice quite room for our own and the kitchen, bathroom, living room was shared with Jaco & Julie. There was also a very nice garden, which was very relaxing after doing sightseeing in a quite busy city.
Jaco and Julie are both very nice and we enjoyed the atmosphere there a lot. They have even a lot of tips, if you want to know where to go out at night or how to get there.
