tldr: price to quality ratio is outstandingly bad.
Pros:
+ The apartment is perfectly located - just in front of the metro station and very close to the Galata Tower. All the main landmarks of Istanbul are within walking distance.
+ Communication was good, host was always online and willing to help (he did help with some issues).
Cons:
- Very noisy at night (everyone is constantly honking right next to the windows).
- The apartment was dirty: we had to buy sponges and rags and wipe all the surfaces ourselves.
- There was a trash under the furniture, left from previous guests.
- The bed linen was old with small spots and holes (clean though).
- There is only 3 mugs and 3 plates in the apartment. It's not very convenient for 4 guests.
- There is no dedicated working space, despite on it was declared in the description.
- Dryer is broken. It does exist, but doesn’t work.
- Baby crib is broken. I wouldn’t risk putting a child there. Good place to dry the clothes though, since the dryer is broken.
- Too tight for 4 adult guests. Would’ve been ok for 2 adults with children, I guess.
- Small bedroom has only one electrical socket (btw, there were some electrical leftovers from the previous guests stuck in there, we had to fix that). You’ll need an extender if you want to charge your devices.
Conclusion:
Not a bad apartment for 1-2 people for a short period of time, if you do not mind the dirt. We’ve been to a lot of places around the Europe, and so far this apartment is the most expensive and the worst generally.
