This space was the absolute highlight of the places we stayed on our trip (and all three places were great.) To start, it is incredibly well located in a hip area with conveniences, shopping, a grocery, restaurants, and King's Cross / St. Pancras nearby. (Try London Kebab in the little strip mall nearby - EXCELLENT food and a great value. Tip - Cash only).
Speaking of the space - it's easy to access, really stylish and fun, and has all of the amenities you could need. Christine was the most communicative and helpful of the owners we dealt with on our trip (by far) and assisted us with info and check-in, etc. even though she was out of the country traveling as well. Cannot recommend this place (and Christine) enough.
I will say this: We stayed there with our two children - 10 and 6. They are super mellow and tend not to get into things they shouldn't. However, if your little one(s) are a little more rambunctious, I might not recommend it for you. It's filled with so many charming and fun things you might find yourself on pins and needles trying to not have them touch anything. :)
