Our three-generation party of five (mother, father, toddler, infant, grandmother) had a comfortable one-week stay at Sharon's house. The best thing was being able to spread out and relax. With three bedrooms upstairs, a large living room downstairs, plus the roomy basement, everyone had privacy and we were able to vary things for the kids even on days when we were mostly at home. The house was clean, the beds were comfortable, communication with Sharon was excellent, the neighborhood was pleasant, street parking was plentiful, and the SEPTA train station was an easy walk: all as advertised. It was a treat to find the basement stocked with puzzles, games, and children's books, and to find helpful guidebooks on the dining room table.
I loved the Weaver's Way food coop (five minute drive) and the Malelani Cafe sandwich/tea shop at 6734 Germantown Ave (betweenPelham Rd & Westview Ave, a 10-15 minute walk).
There were some downsides. First, if you do want to spend a lot of time in Philadelphia proper, you will soon get tired of either taking the train or driving. We would have regretted our choice of lodging if we hadn't been hampered by the kids and our desire to save money for a week's stay. Second, the fact that the trains only run once an hour makes this option somewhat less convenient than we had anticipated. Third, there is no bathroom on the ground floor. We also got pretty tired of going upstairs or to the basement every time the toddler needed to use the toilet! Fourth, the kitchen does not have a dishwasher. Finally, while the kitchen is functional it is, like many rental kitchens, eccentric. There are too many pots, making it hard to negotiate the cupboards; at the same time, there aren't really enough oven-ready pans. The knives are dull and the manual can opener is broken.
All in all we feel we made the right choice and would recommend the house to other travelers with similar needs.
