Jo is incredibly efficient at making sure you have absolutely everything you need to check yourself in and out and make yourself at home. This is probably one of the largest studios I've stayed at in the Causeway Bay Area, and possibly one of the nicest as well. It's on a 7th floor but there is an elevator. There is a small fridge if you need to store anything, and a microwave for those late night snacks! Shower I great, you don't really have to wait long to get hot water (like in some other buildings) and the water pressure is great.
Very short walk to the Causeway Bay MTR and you can take the A11 bus to the airport from just outside the apartment. Being so close to Causeway Bay means you are super close to all the shopping your little heart might desire, and to some very tasty food options (we discovered an excellent ramen place around the corner we'd never seen before.
Overall a great experience with Jo - she makes herself available and anticipates needs before they occur - by providing you all the information you could need to be comfortable at her studio.
