Viewing a clean and nicely furnished unit gives a good impression to our Prospect (Buyer/Tenant) as well as a instant plus-point to our Client (Seller/ Landlord). Minimum noise pollution from the environment e.g. Lift Lobby and unblocked view are also plus-points.
Afterall whoever lives in or owns the unit would derive a lot of pleasure, peace, quiet and tranquility for a well-chosen unit.
