The whole communication before the arrival was great and comprehensive. The whole process of filling-in the pre-arrival registration as well as the self check-in has been described properly and was also manageable after a long day of travelling. Kim, the digital concierge, was always reachable for us and provided us with all the necessary information e.g. the check-out procedure.
However, the studio without window is definitely smaller than it appears on the pictures. With two persons and luggage (two big backpacks) the place was packed. Furthermore you should be aware that the walls are thin and you will hear other guests on the hallway or just showering. If you're a light sleeper don't forget to pack some ear plugs.
Despite this, the location is awesome. It's close to the subway station Bugis and some local Food Hawkers. If you're visiting Singapore on a budget, I would definitely recommend staying here.
