The interior is very outdated. Bathrooms are super old (think separate taps for hot and cold water) and the toilets don't flush well. There is a pretty serious ant problems - they will come out if you leave anything on the kitchen counter for more than two minutes. Not all lights work and some door knobs are very hard to operate. You can also hear the neighbors very well.
The check-in process was confusing and the initial communication from the host was slow.
The Internet works well. Overall the apartment is usable.
