If you are coming to Istanbul, this is where you should stay. Stop searching, and book it.
From the moment we booked Dodo was proactive and clear in communication. He helped set up airport transfers, provided a guide to the neighborhood, and made us feel that our trip was already off to a great start. From here, it only went up.
For us, the things that matter most when booking are location, ease of living, cleanliness. In all of these areas, this rates 5 stars. For the short version of the review - you will thoroughly enjoy your time here and have no regrets. You'll also likely leave with a new friend in Dodo.

First, location: Some will say to stay in Sultanahmet but I would suggest that these people are wrong. Right near the Galata Tower, this residence offers everything a great location has. It is extremely easy to get from here to anywhere you want; it is an easy walk to the bridge or to the metro. There is an endless supply of good restaurants and interesting shops and a vibrant atmosphere all day and night. While being in the middle of everything, the street you will be on is surprisingly quiet and provides a chance to get needed rest.
Second, ease of living: Dodo has it all. The kitchen had every utensil I could have possibly needed. The bathroom was stocked with extras in case I needed it. The television had channels in English (important only for some but nice for us). I brought my 4-year-old daughter with me and Dodo's place provided no obstacles for that either. The beds were comfortable, the rooms got dark enough and quiet enough. The water pressure was great. There is a market next door open 24 hours which is sufficient for any last-minute needs. There are multiple grocers a short walk away if you need to make a more substantial run. I could go on and on. Ultimately the rental provided no obstacle to overcome which only enhanced our time in Istanbul and let us focus on having fun.
Third, cleanliness: This can be tricky in Europe. The downside to staying in beautiful old buildings tends to be that they are old and therefore can be a bit musty and dirty. I am happy to report that at no point did we feel grossed out or unclean while staying at Dodo's.
