Convenient location (aprox 35min subway to the center), but hood can be quite dirty and noisy sometimes (you can search Geylang on internet).
Landlord is always very fast on replying messages, but never seen him in 5mth. Shopping mall PLQ is 10min walking from the apartment (very convenient) and cleaning staff is very friendly. Don't try to make friends in the apartment, normally the communication with other guests is just nothing.
In short, the apartment and location are okay if you want to visit sg or live there for a short period. However, if you want a long stay I would recommend HDB.
