tl;dr - Extra-comfy bed, perfectly arranged and personally decorated spaces, super quiet and cosy location given the proximity to bustling areas, impeccable communication.
Caroline's place is a true, true gem – perfect for a couple or solo guest. The location is a quiet close, just off the main drag of Whitechapel/Mile End road. It's actually impossible to believe how tranquil and secluded the place is given the bustle of the surrounding area. Once you're in, you feel tucked away from everything happening outside.
The space itself couldn't be kitted out better. It feels so much bigger than it looks in the photos; everything is so well-considered and fits in perfectly. You feel so at home upon arrival; there are so many interesting books/photos/pieces of art dotted around that Caroline has collected whilst travelling, you'll wish she was there so you could hear all the stories behind them. The kitchen is big enough to cook a big meal in and it's clear from the outset that you can use anything in the house. The bathroom is great, there's Netflix etc if that's your bag, the bedroom is plenty big enough and the bed is like sleeping on a cloud. Honestly there are no faults here.
Caroline was super helpful throughout our stay, very efficient at communicating and seems incredibly friendly. Check-in couldn't have been smoother.
In summary, stay here if it's available. You'll have the best time.
