First of all thank you for hosting us!
A few things to consider when choosing this flat:
1. If the location is your one and only priority - Go for it. The location is amazing. If you want to you can reach everything by foot, even the banking district up north.
2. The WiFi (as of September 2021) is bad.
3. The furniture could use a little refresh/adjustment.
Conclusion: If you spend little in the flat, go for it nothing to complain about. However, if you need to "work from home" during your stay, you might need a well equipped data plan.
