The apartment is pretty spacious, but there are several things you should consider.
It's a first floor apartment, with the windows overlooking the street. Sometimes it's noisy and at least a couple times a day someone is smoking near the window.
It was pretty cold in September, The apartment uses a central heating system, so the temperature was between 18 and 19 deg.
Wi-Fi download speed was less then 5 mbit/s
And finally please pay attention that beddings and towels are not provided at least for 1week+ staying. I missed that from description, and was additionally notified only a couple of hours prior to check-in
To summarize, I'd say that the apartment is a nice option for a short term staying in warm months or when central heating is working. But for longer staying I'd consider the details mentioned above.
