We were a family of 6 people staying in Jennifer's 3 bedroom apartment for 2 weeks.
The apartment was clean but there was not much space to put our stuff as she had her closets full. She was happy to come and free up some space the next day when we asked for it (however still very little for 6 people).
There is no washing machine use or cooking allowed in the apartment. She is very particular about that.
Also she has very specific instructions on how her guests should use the apartment including how to clean (floor/carpet) and how to use the dining table (have to put a cloth before using the wooden table).
The apartment is in a great location (very close to chestnut street where you can find great shops/restaurants, the views are also gorgeous all around) and Jennifer is responsive however I don't recommend it for a large family with kids if cooking and laundry/cleaning is necessary.
