I had some issues in my stay.
First, as Jan went traveling for the new year's eve, he sent her friend to give me the keys. Although she seemed nice, she was late for an hour and didn't speak English, which obviously didn't help the communication.
The apartment was okay, but the bed was very uncomfortable. Actually, it is not a double bed, but two single beds pulled together, and one mattress is broken. I had to open the sofa bed and my girlfriend and I slept there, what wasn't so bad. Additionally, towels were smelly and didn't seem clean.
The location was good, next to the metro and close by foot to the old city.
All in all, I wouldn't recommend it regarding the price.
