We had an excellent stay at Abigail & Gwen's place! Vadhel helped us with the check-in even though we arrived a bit late to Singapore. The location turned out fantastic: many interesting spots are in walking distance, and there are a few restaurants and bars in the same street (yet there's no noise at night). The apartment is small but my wife and I had enough space and even spent a significant part of our stay working from the apartment. Everything was clean and well-furnished. The wi-fi was pretty good (we measured 49Mbps up/39Mbps down), but it had some hiccups — nothing that prevented us from working though.
Vadhel was also very helpful by keeping our luggage for the day after we checked out, which was very convenient for us as we had a late flight from Singapore. I would highly recommend this apartment to couples or single travelers.
