This apartment is as large and clean as the photos show (very spacious for HK standards) and is located in a convenient, safe and quieter part of Mongkok. It is about 5 - 7 mins walk from the Mongkok MTR station and less to the Mongkok East station. The shower is also large for HK standards and is separate toilet from the toilet rather than a cupboard-sized combined shower and toilet like in many HK apartments. The bed was also very comfortable.
Phillip was very responsive and helpful as a host. If you like coffee and want to avoid Starbucks, try the nearby Black Sugar on Peace Avenue (I think), and do try the egg custard tarts and pineapple buns at Kam Wah Cafe less than 10 mins walk.
We would definitely recommend staying here and would definitely do so again on our next visit. Thanks Phillip and Sisy!
