The positives - great location, nice rooms, quiet off the street, helpful staff. Seemed very popular location for upper crust locals to gather. One block to subway; lots of restaurants in the area. If this were a pleasure trip, I would have been much more satisfied.
The negatives - crawling under the desk to unplug the lamp to use the only plug for my computer, others had no plug near the desk; poor lighting for reading for work; very expensive services (1 euro to stamp and mail postcards, car service was nearly triple a cab for airport, internet access from room); eggs at breakfast that tasted like powdered mix; very expensive bar (the deal of the day was 9 euro for a "pint" of heineken in an unmarked glass; bath tub with six inch wing to keep shower water off the floor; maids who turned off power in the room which drained the batteries of computer and phone that were charging; and relatively expensive. I expect more from Renaissance brand hotels.
