The building is a bit old but the hosts have done an excellent job with the room. Hong (the host) was extremely helpful and proactive, and preemptively covered most potential concerns with the apartment with very clear instructions. For what you pay for this is an excellent place to stay.
One thing to note however is that the AC can be very loud, so you might have to deal with some noise on hot evenings. I think this should be fine for short stays but may be an issue for long ones.
