Communicating with Charlotte was quick, great and easy. She gave us lots of good tipps for our stay in London - among others booking Sky Garden 3 weeks in advance - which was brilliant. There are buses leaving directly in front of the house which we really appreciated when coming back after a long day in London. Sydenham station is good to reach where you can get and top up oyster cards (the cards for the kids were a problem though, as you need a member of staff to put a child's reduction on it so better follow Charlotte's advice and get them beforehand!). We stayed in the flat with 5 people which was ok; we'd recommend it for 4 people the most, though. The house seems to be quite new, the shower is really nice. Checking in and out was no problem at all. Thanks again, Charlotte!
