We have had the worst experience at this hotel, (I am a frequent traveller so I would have a good idea).
Cons:
1) Mould in the bathroom, white marks on the tiles, looked like pubic hair in the shower area, and near the sink
2) House cleaning are appalling, for example they do Not vacuum/hoover the floor in the room, they do not change bed linen, don't wash, clean the bathroom, hence the room becomes very dirty, dusty and untidy
3) Dust is left on the tea tray in the room
4) Don't get complimentary water everyday (meant to get at least 2 bottles)
5) Strange smell in the room
6) Metro right next to the hotel, so it's very loud constantly, no peace and quiet
7) Breakfast options are very limited, and its not tasty, it's very poor
8) Every time you call reception, the lady receptionist sounds very distressed on the phone, almost like you have disturbed her from doing something important
9) No staff to take luggage to your room, we were on the 10th floor! It's all self service
10) Gym is extremely tiny, dumbells max weight is only 10 kg
11) Room size is very small, not fit for a family or even 2 people (we were 2 parents with a baby)
This is really a zero star hotel, and no way near 4 stars!
(Definitely no pros)
