After a stay of 8 months, I can say that overall the flat is nice & was comfortable.
The flat is well outside the city-proper, but offers city views, a skyline with lots of buildings & construction of one of the most growing districts of the İstanbul area, but also a lush park directly at street level and viewable from the large living room windows.
There are definitely some things to consider if choosing a stay at this property (or in Esenyurt, in general). This area is not the best for tourists, if you’re coming to İstanbul for touristic reasons, stay closer to Beyoğlu, Cihangir, Galata, or Fatih. This area is quite far out even by car. However, it is quite affordable compared to those other places. If you choose Esenyurt for a holiday, you will find a Metrobus station relatively close to this property (about 20 minute walk, mostly through a park), then a 60 - 90 minute ride in a congested bus (don’t bother waiting for the next ‘empty’ bus - they’re all that full).
If you’re coming to İstanbul as a Digital Nomad, you may find this location to serve you well. The internet is sometimes inconsistent, but generally strong when it works. Throughout Türkiye there seems to be problems with municipalities providing consistent water & power services, this building was no exception. But the AC worked well all summer & heat was fine in winter (when power & water functioned normally). If you have or rent a car, you can get to tourist areas within 90-120 minutes & then retreat back to your apartment in the sky for life near to the largest city in Europe.
The host was kind & tried to be helpful through my stay. The building & complex is under construction & the workers & site management personnel weren’t too friendly nor helpful - for instance whenever a work crew cut power to my flat/floor neither the workers nor the site management seemed too anxious about getting it restored in any bit of a timely fashion. This won’t likely be a problem for much longer as it seemed the 25th -29th floors were well on their way to project completion.
Overall, if you have patience and aren’t coming to the world’s largest transcontinental city to be a tourist, this place might make a nice home-away-from-home.
