Very clean and nice place with a good location (5 min walk to U-bahn and then 10 minutes to the city center). Check in was smooth and on time.
Drawbacks:
* Bed is extremely soft and pillows are too large (in a bad sense) . So after sleeping in bed your back and your neck will hurt. If you want stay here for more than 1 night, better start sleeping on the sofa. Don't even try this nightmare bed.
* Central heating was off(or broken?) and it was really cold in the flat
* There were issues with hot water. Water boiler showed error and didn't heat anything. Host didn't respond on time so we needed to google how to fix this error and reboot the boiler.
* Heater for towels is broken and constantly leaks on the floor.
* Some furniture were also broken, but that's not a big issue.
Generally, apartment was well below our expectations. Will suit well for 1 night stay, but if you want to stay longer, better chose something else.
