If you stay in David's Castle, you will...
...meet an amazing host with lots of stories, tips for London highlights you may not find in regular tourist guidebooks and lots of opinions worth discussing.
...get helpful English language and culture tutorials for any and every level.
...maybe even get a private guided tour at the British Museum, the British Library or the National Gallery
...get freshly squeezed orange juice and nice treats (healthy bread and cereals, fresh fruit, occasional bacon) for breakfast.
...be woken by his cat when it jumps in your bed or loudly meows in the morning.
...be amazed by David's unusual up-side-down house.
...take lovely outside showers after getting used to the idea that neighbours won't watch.
...meet people from all over.
...share a bedroom and a bathroom with lots of different and often snoring adult strangers.
...feel slightly bad for coming home late and maybe waking the other guests when getting ready for bed.
...meet interesting people from all over.
...
Honestly, it was the most interesting and rewarding home and home stay I have ever had in the Western world. As an English teacher and culture vulture myself, David's tips, stories and life philosophies were more valuable than most teacher training courses I attended could claim.
However, you need to be open-minded, not too afraid of sharing your personal space and not too fussy about cleanliness to enjoy it to the fullest:
Wheres I'd definitely love to retun, my more private, quiet-loving olleague definitely will not do so.
But if meeting different and interesting people from all over the world in a unique setting is your cup of tea, you just mustn't miss a few days and nights at David's Castle!
