Stayed in Wonderful Studio. It's very modern, clean and with lots of amenities; even a washing machine with detergent included besides more usual coffee maker, tea selection, toiletries, and so on. Jetted bathtub is also a plus. On the small bit of limitations, the room was a bit small, not much space to move. It's fine for couple days but longer stays or staying as a couple would be a challenge (probably opt for a larger room). And having breakfast included was nice, the selection was more on the local style food but there were some Western selection as well. The lounge area is nice but it's a bit dark and during the day (after breakfast) selection is limited to fruit cup and cheesecake (along with coffee machine and some soft drinks), which is not much compared to other hotels around.
The location with proximity to MRT, coffee shops and restaurants, convenience shops, was very good.
Overall, Tango is a good hotel to stay and enjoy.
