Stay was okay.
Pros:
- Perfect connection to airport
- room looks nice, size is quite okay
- city center in walking distance (15 to 20 min) or also good connection
- washer and dryer in the flat (did not use it, but good nonetheless)
- bathroom and shower was good (but not private and therefore not always super clean)
Cons:
- Bed was not very comfortable (we have high standards in that area, but hey, we are basically booking a place to sleep).
- Room was SUPER noisy (the bathrooms fan was very loud and bathroom was directly adjacent to our room; the windows practically are zero soundproof and passing trams and buses sounded like they where right next to the bed + extremely noisy road work started at midnight; door to the our private room was not soundproof either, so you could hear when other guest came in or walked out; in short: thank God for earplugs, otherwise I would not have found sleep)
