Philly's apartment is awesome, and totally worth the 7 floor walk up! The apartment is in an old building but it's completely modernized, with a very cool design and great cement floors. It was very clean and very comfortable, with more than enough space for the two of us. And the rooftop was a very nice place to relax at the end of the day. The location was great too--right near the MTR. Philly was a very friendly and helpful host as well. I hope to stay at her place again the next time I'm in Hong Kong!
