Although the location for Annex is a bit difficult to find out as it is easily to confuse with the main building, the overall cleanliness is for both common area and inside the flat.
The space inside the flat is big enough with separate bathroom and toilet bowl, balcony, kitchen equipment and tableware. However, drawer is not enough for 4 person.
View is excellence for higher floor. The self-pick up of door key is easy and very convenience especially when check in at late night.
