Overall, the staff are lovely and helpful. However, my stay was not great (this largely out of the hands of the staff and they did their best to help me).
I stayed for 2 nights and had to change rooms twice because of noise: once due to refurbishment work (drilling directly above me) and once due to a disco event taking place a level below. On the second night, a member of staff entered my room at half past midnight and woke me up, presumably because my move hadn't been logged on the system.
The hotel has been refurbished recently, and, while the rooms look nice, the new look isnt practical. Instead of bedside tables there are weird stool-type things that have a concave top and a hole in the middle. So you cant put a drink or your jewellery on them because it'll fall over or slip down the hole. The bathroom lighting is terrible and you cant see yourself unless you stand away from the mirror to catch the overhead lighting.
The hotel has a water machine on each floor and carafes in each room - eco friendly - but there was no sparkling water on 4 different floors because the CO2 needed replacing.
The room temperature is like a furnace and no amount of changing the thermostat will affect it.
There were other little niggles, none of which were terrible, but add up to the fsct that this does not feel like a 4* hotel. If you want cheap and cheerful, stay here. If you want 4* service and surroundings, go round the corner to the Intercontinental.
