The place was fine: it exists, everything more or less worked etc, but personally I'd not recommend it to anyone. The apartment was generally just drab / run down; not at all as we expected. It wasn't even particularly cheap; there are better options.
The apartment is on a very noisy street. Even with the windows and "balcony" door shut completely, it was at times difficult to hold a conversation inside the apartment due to the noise (esp in the lounge room and main bedroom).
The beds in particular were terrible: squeaky camp-style bases with lousy mattresses.
Getting the key from the owners is a bit of a hassle. The main office is not particularly close to the apartment itself and while it is open 24-hrs (and the staff were very friendly and professional) and close (ish) to a subway, you want to allow some time to collecting the key and then walking back to the apartment itself.
