When we first arrived the room we were given was terribly small, had a window with a view of a wall with pipes, and had the constant noise of the boiler running above the room. Additionally, there was a lot of noise from other guests who were drunk, breaking plates, and a strong cigarette smell wafting from the corridor. And the kettle in the room was broken and extremely dirty (leaving rusty bits in the water after boiling).
The next morning we asked for a different room and the new room was significantly better (much larger, quieter, and with an actual window, although there was some street noise). There was still some cigarette smell coming into the room from the corridor, however.
Service from the front desk was nice, they were agreeable and helped us with storing our baggage. After-hours and housekeeping was another story, as they did not speak English very well and couldn't understand us. Once they forgot to put towels in our room and when we requested them we received dirty ones.
Another thing to note is that the hotel is located in an enclave that is difficult to access by taxi after 11pm since they close all the entrances but one. And I think they advertise that they have gym facilities, but they do not. And the TV did not work for a day because they forgot to pay their subscription.
Overall, it was ok as a place to sleep and store our bags before our flight. But otherwise, I certainly wouldn't call it a "luxury" business hotel in any way. Budget at best.
