We'll be taking advantage of our airline's ability to book stopovers to stay in Istanbul as part of our main trip to Egypt. We will likely be spending 9 nights in Egypt and can do the Turkey stopover either at the beginning or end of the trip. We're planning to leave the states right after Christmas -- sometime between 12/27 and 12/31 and can spend up to 3 to 5 nights in Istanbul. We're in our thirties and mainly interested in historic and other sites. We don't care at all about nightlife/clubbing. Unfortunately, I think that means we need to stay in the touristy section of Sultanahmet. So, my main questions are:
1) Is it a mistake to visit Istanbul this time of year? Is there any particular reason to put Turkey at the beginning or end of our trip? I am mainly thinking about holidays or other events that make one timeslot worse versus the other.
2) Is Sultanahmet indeed the right choice and where should we stay? I really love the look, feel, reviews, etc. of the Witt Suites but, alas, they are not in Sultanahmet. We are not opposed to universal quality names like Ritz or Four Seasons, but prefer to go more boutique when there are quality options. Not looking for an excuse to spend big, but budget isn't very constrained.
Thanks in advance!
