The location is very good, though we did have a hard time finding for the first time, thanks to the Google Map directions. After which we found out it is near the subway and have many departmental stores, supermarkets and eateries around the area. There are 3 convenient stores near the hotel too. Oasis 21 can be reached by foot, if you don't mind walking, like we did.
The hotel is the only one which offered us complementary coffee with an espresso machine at the lobby, among all that we had stayed this trip. They even provide paper cups with cover which you could take away to your room or bring along while you are out. It also offered 2 lab tops at the lobby for you to use, except the default language is Japanese which is a little troublesome for us.
The staff were helpful when you asked them for information, except they were all not smiling liked others we met elsewhere. So let you feel that they are more like on duty but not with enthusiasm or passion in serving.
My husband likes this hotel especially the location and the amenities around it, so would come back or recommend friends to this hotel. Personally, I do like this hotel but find that at its grade, the rates are of the high side even it's on offer. Actually the highest of all the similar grade hotels we had stayed during this trip.
