The apartment is in a very convenient location as you have everything you need nearby and it's in walking distance to the central area of Causeway Bay and Wan Chai. It's also well connected by public transport. It's also pretty quiet in the room considering it is located in a busy area.
I know how small the apartments are in HK in general, but this room and its toilet are really tiny and I wouldn't recommend more than 1 traveller to stay there as you can barely open 1 big luggage on the floor and there is only 1 small wardrobe. It's also definitely not as new and clean as shown in the photos. They added 2 metal boards mounted onto the wall as tables and make the space even smaller. If the bed wasn't elevated so that we can put the baggages under the bed, we wouldn't even have space to pass.
As for the host, Amarjeet is very friendly and responsive. We got clear instructions for check-in and we got no problem finding the apartment.
