Just completed a 5-night stay. Cancelled our reservation at the Conrad since the Bomonti pre-upgraded us to a suite. Very glad we did! Great hotel, with an excellent concierge lounge and superb amenities. An extensive breakfast was offered in the main dining room or a smaller and quieter breakfast in the Executive lounge. The EL was open until 2300 and complimentary alcoholic drinks were offered from 1800-2000 hrs with heavy hors d'oevures and desserts.
Our suite was on the 26th floor with amazing views (floor to ceiling windows). The suite had a separate bedroom and living room. They allowed two free rollaway beds for our kids. Two separate bathrooms (heated floor) added to our comfort. Teenage son enjoyed the gym and daughter enjoyed the indoor pool. The suite, facilities and EL gave us the extra space needed after great days exploring beautiful Istanbul!
Some may consider this to be a bit far from old town but a taxi costs around 20 TL each way and we enjoyed the taxi ride. For your return, be sure to bring a Hilton street map with you (from the concierge) to show the taxi driver so that he knows which Hilton and its proper location.
