I would recommend the room for a stay in Singapore of an intermediate duration if you're not sensitive when it comes to cleanness
A definite plus is the location in an authentic HDB with several means of transportation available. Redhill MRT station is a 15-minute-walk away. However, you'll usually be much faster if you take the bus at Opp Pacific Tech Centre which is just a five-minute-walk away or, if you're lucky, the line 63 which departs right in front of the house works for you.
The main issue is the low hygienic standard. Joyce had announced that the commonly used rooms (esp. bathrooms and kitchen) would be cleaned weekly. However, the toilets were clearly not cleaned once during my entire stay of over a month. The mix of pee stains and pubic hair was downright disgusting.
In my opinion, this can only be excused by the relatively low price compared to other airbnbs. However, if you are planning a stay of several months you'll easily find a clean, modern condominium with a pool and a gym for a lower rate in the respective facebook-groups etc.
