Stayed 2 nights in Ibis Novena. Overall it's standard Ibis hotels. Room was quite small, but it's clean. Breakfast was standard. Friendly staff. The hotel offers shuttle to Novena MRT station and few hospitals in Novena, but If you missed the shuttle, you can walk to MRT station, takes around 10 minutes.
Front desk was very helpful when I accidentaly left my phone charging in the room after I checked out.
Would definitely stay here again next time.
