My wife and I are digital nomads, and we stayed here for about two months.
There's a decent amount of room here - enough for two people, but anyone with a kid might be cramped. Hook up your console to the TV (we had a Switch).
Upsides:
* The host and their representative are very quick to respond to e-mails.
* As locations go, you're close to plenty of restaurants, an office supply store, metro line 2, and plenty more. You're one stop from tourist central (Taksim)
Neutral points
* This is basically 'Ikea land' - furniture is functional, not necessarily stylish.
* This place is furnished - barely... No cleaning products, just enough dishes to be useful... and almost nothing else. Expect to buy any consumables you might need.
There are several downsides of the 'annoying' variety:
* Very little soundproofing - you can hear the seagulls walking on the roof overhead, the neighbors on the other side of the apartment, the neighbors below you, the calls to prayer...
* The shower seems to take a fair bit of time to heat up, and then likes to oscillate between way too hot and lukewarm.
* Despite the elevator having a '5' button and the apartment being on the 5th floor, you have to take it to 4 and walk the last flight up. Not a problem for most, but annoying with you're carrying 10 liters of water.
* Around once a day, one or more of the building's amenities would decide to stop working: the elevator, the power, the hot water, the internet....
* The wi-fi available here is an extender placed on the floor, and it's unclear how many other apartments it's shared with. It's usually fast enough, but would go out often enough to be annoying.
