Hilton Prague
Just checked out of the Hilton. Here are my thoughts. Checked in and was upgraded to the exec floors. As gold or diamond, you can check in on the 8th floor (exec check in). Room was fine, but nothing special. High speed internet is available at a cost (did not use it, so don't know the cost).
The best thing about the hotel is the exec lounge. Great breakfast and great food spread during the whole day. Huge variety of sodoas, waters and alcohol. Best exec lounge at a Hilton I've been in. 3 high speed internet terminals and a huge TV on one side. The lounge is huge. For those of you who know the Hilton NY lounge, it is at least 4 times the size and newish.
The hotel has its own fleet of cabs. Prepaid cab ride to/from the airport is 25 euros.
Although not being in the city centre, it is easily accessible by metro or cab (6 euros). The metro station is 3 min walking and the city centre is two or three stops away.
