We enjoyed our week-long stay at Hsing-Yu's place. The location could not have been better - right above the MRT; 7-11 around the corner; <10mins to the famous Yongkang (eat) street; the original Din Tai Fung and a yummy bakery to boot. The area felt quiet safe even late in the evening and the building is always manned (the evening guard is very friendly).
The exterior of the building may be a little worn but rest assured the interior has been recently refurbished; equipped with new appliances; an enclosed balcony for drying clothes; shower with good water pressure. The layout is well thought out, maximising the space so it was quiet comfortable for the 2 of us and would be cosy for a family of 3. As it's located near a intersection, traffic noise echoes into the unit but it quietens down by 11pm so consider bringing earplugs if noise sensitive. Sleeping area is on mezzanine level with a futon mattress which at first took some getting used to but otherwise space is sufficient.
Our interaction with Hsing-Yu has very been very positive, she is responsive, attentive, knowledgeable and is always keen to assist.
