Goodmorning2U, sounds like you had a great stay at the Four Seasons Nile Plaza. This is my preference over the Four Seasons First Residence. The NP wins on location, spectacular views, spa and gym. Staff at both hotels are professional and look after guests well. Did you try the limousine service in addition to the airport pick up? Looking forward to your next impressions.
