I had a great time at Kelly's apartment in Williamsburg! It is exactly as described: spacious, spotlessly clean, and furnished with taste, lacking nothing. Being a ground floor apartment, it is a little dark, but that didn't bother me. The location is superb, just one stop on the L-Train to Manhattan, and the Subway stop is literally right around the corner. There are tons of restaurant and cafes within a five minute walking distance.
Kelly gave me a very early check-in, which was great, as I arrived early morning from a long transatlantic flight, and a super late check out for a reasonable extra fee. Communication was fine. I recommend the place with all my heart.
