"Overall, we had a pleasant stay at the Shanghai Marriott Marquis. The location is excellent and makes it a great base for exploring the city. Our room was a good size and offered the level of comfort you'd expect from a Marriott property.
That said, there were a few areas that could be improved. Housekeeping was a little inconsistent. On more than one occasion, the soap or shower gel dispensers weren't refilled, and some glass surfaces still had water marks, as though they had only been wiped over quickly. These are relatively minor issues, but they're not what you'd expect from a hotel of this standard.
The concierge team could also be more proactive. A warmer welcome and a few more smiles would make guests feel much more valued. Unfortunately, the member of staff responsible for arranging taxis was particularly rude to my wife, which was disappointing and something I hope management addresses.
One thing that genuinely surprised me was that the final bill was calculated using the exchange rate on the day of checkout rather than check-in. I'd recommend paying upfront if possible, unless you're happy to take the risk that exchange rates move in your favour.
Finally, be aware that the hotel's laundry service is exceptionally expensive. I'd strongly recommend using one of the many local laundries instead, as you'll save a significant amount.
Despite these criticisms, the hotel still provides the quality and comfort you'd expect from Marriott and I would return."
