I was so glad to have found a laundromat in Istanbul! It is a rare find. But leave it up to a…read morecurious and determined foreigner to find one! And it was a short distance from the hotel where we were staying.
Although, I must warn that if the GPS says "Ten minute walk" just keep in mind, that may include loads of hills and/or steps! Best bet is to taxi.
The laundromat is on a little corner across from a market and some other shops. But it is a very clean and well lit little place with great instructions above the machines. And laundry soap is included in the wash.
The reason why we chose this laundromat is because the in house service at the hotel was just too expensive for the load of three people we had to wash for.
Besides, this was much more adventurous.
