Unit's location is perfect. You can find any food, any restaurant option within a 5-10 minute walking radius, which was very important as we traveled with a kid.
Unit isn't massive in size - although 7 of us fit well enough, it isn't the ideal unit to spend time indoors.
Again, on the location - you can walk to Moda district, Bahariye street, to the docks easily. We also crossed the Bosphorus multiple times by taking ferry from Kadikoy to Karakoy, Eminonu and Kabatas, which was super convenient. You can also walk to the main bus station, in 10 minutes, that has buses traveling to various locations in the Anatolian side. For example, we took our kid to Emaar shopping mall to visit the aquarium and to the Akasya shopping mall to visit Kidzania by using buses that took off from this station.
