This is a typical large international calibre Sheraton, efficient and reasonably well located nearby the main railway station, and on one of the Metro lines. If you take a train in from the airport, it is a short two block walk to the hotel from the station.
Rooms are large and comfortable. Breakfast is a large buffet in the second level restaurant will lots of choice. As for alternatives, it depends on what you are looking for. The Hilton has a better location for museums and city touring, but then where do you need to be in the city? The Four Points will be cheaper, but not as posh.
If breakfast is included in your rate, ensure you have this noted on your reservation and bring a copy with you. The front desk often insists the rate and details on your res are not what they are prepared to honour.
Enjoy your stay.
