Our group (7 people) stayed at Betty and Fred's apartment for 4 nights. It was definitely too small for 7 people but we managed to squeeze everyone in. Fred was kind enough to lend us extra mattress for free. We didn't meet Betty but Fred was amazing. He texted us a very detailed pictorial instruction on how to check in and all the necessary information. Even after that, Fred was waiting for us in the lobby to help us check-in. He also gave us a lot of information about the apartment and surrounding area.
Definitely A+++ in terms of the customer service.
The apartment itself, although small, it was more than adequate. Location is great as it's very near the MBS, Merlion park and China town. It is situated between 2 MRT station which you can access easily via underground walkway. It's also near the Lau Pa Sat food court which we frequented first night we were there.
The amenities of the apartment itself was sufficient. Comfortable bed, clean bathroom, kettle, microwave, washing machine, cups and mugs. Saying that, there was not many plates or cutleries. This wasn't a problem for us as we went out to eat all the time but might be problems for some. Having said that there was no real dinning / lounge area within the flat either. All the equipment in the apartment was functioning well. We didn't have any problems with lighting.
The building itself is equipped with great facilities. Four swimming pools and very modern gym and sauna. It even has karaoke facility. The sky deck on the 44th floor was a great addition. It provides beautiful scenery of Singapore Bay Area, especially during the night. We spent a bit of time by the sky deck.
Overall we enjoyed our stay. I would certainly recommend Betty and Fred's place but maybe not for 7 people unless you don't mind quite intimate sharing.
