I'm 26, living and working in London.
Jennifer's apartment was absolutely wonderful. The bedroom was large and very quiet and nicely appointed. While she was not there her roommate was extremely friendly, non-obtrusive and helpful. Location was perfect, close to a major tube station (Holborn) and within easy walking distance to some of the best parts of London (i.e. Covent Garden, Soho). If you are so lucky as to see her place available I would suggest you grab the opportunity as quickly as possible.
Jennifer was a very polite, punctual, clean and communicative guest. I'd definitely have her and her boyfriend back. My only complaint is that they left the living room window wide open the day before hurricane Sandy arrived and it resulted in some water damage to my windowsill.
Jennifer and her friend were really nice people who took good care of my place and left it totally clean! I would host them anytime!
