My suggestion is to improve everything, wifi
The service and food are honest, I paid a lot but what I got was not satisfying for me. I stayed for 4 nights, the breakfast menu was just the same, nothing special. In my personal opinion, staying in a business suite doesn't feel like a suite. Remember, this is my opinion. There is nothing special in the room. The staff are also not very friendly except for one lady, I forgot her name at the reception who was always friendly to me. In the restaurant, it's not that great.
