A friend of mine recently stayed in this hotel and “lost” her Cartier diamond bracelet. The hotel didn’t want to take responsibility of the missing item nor did they attempt to compensate. My friend later discovered that other guests had similar experiences. Shocking service given the brand and the location of this particular chain. We will not be staying here again.

So-called 5 star. Pretty shabby. OK if someone else is paying.

Great location. Great breakfast. Rooms and facilities very out dated.

The location is great and just a few minutes away from the tube. Though the room -2 single beds- was small and dated, especially taken into consideration this is a 5 star hotel. The staff is friendly and helpful. (continental) breakfast is limited but decent. All in all not worth it when looking at the price you pay for all this.

The meeting room facilities are very good, with the only defect of being in the lower ground level. The food was great, both for the lunch buffet and for the social dinner. The staff was kind, helpful and professional at all times.
