The flat is in Soho, a gentrified area. It is a mixed area full hip and trendy restaurants, bars and shops. In additional to Chinese, you will hear almost every possible language on Earth especially when all the expats/migrants show up after work to chill.
You would also find the old Hong Kong on the street—an old fashioned noodle shop, a mahjong place, a few massage parlors and vendors owned by old people. The neighborhood is quiet in the morning but can get busy at night til late during weekend… actually the action may even start on Thursday. This is definitely a great location for travelers who seek actions and culture.
That being said, the space Lulu offers is spacious and it is a sanctuary from the crowd on the street. Lulu responses very promptly and the check-in and check-out process is very simple. It is in an older building, so be ready to climb 8 short flights of stairs.
