Traveling with children and in a big city like Istanbul need not be a problem for you. Don't worry about breakable décor, little messes, bored kids or grumpy downstairs guests; do not ponder about the easiest mode of travel inside the city and whether you will have to climb hills and hilltops with a kid in you arms...
Brandname hotels like Four Seasons, Conrad, Hilton and Swiss already offer you many great facillities inside the hotel such as sound-proof decor and sometimes a playground and even babysitting services. Others also pamper you with a convenient location -being next to the metro or a taxi stop. Most brand hotels are also located in the social and commercial centers of the city, such as Beşiktaş and Taksim. This will allow you to entertain your kids at the nearest McDonald's, park or mall.
If you are looking for a less big hotel, family-run pensions and motels are your next best option. There is an abundancy of those in coastal cities of Turkey and inside Istanbul around Sultanahmet.
Check out some of best picks listed below. Most of these hotels tend to have "family" rooms.
