The only good thing about this place was the proximity to the lake and train station (tifenbrunen).
The studio is too small for 3 people, I would say it's just enough for two and only for budget travelers.
With the amount paid, It was my fault to expect a much better place but nevertheless lesson learned that it's good to pay the same amount or more but get a bigger accommodation perhaps on the outskirts of city or do a proper check before. The pictures of this accommodation are very deceiving.
If you're on budget and two persons then this place fits.
Cheers!
