This place was great like everyone said, the location was perfect. We felt very safe staying here. The 6 floors was quite a workout, and there is no AC but I believe this is quite normal for Europe.
The downfall for us was that the WiFi was not working. Marc was very responsive to us about this, but we could never get it to work even after restarting the modem box several times. Marc was very apologetic and offered to issue a partial refund because of this issue, which I appreciated a lot.
All in all, I would definitely recommend it. Just make sure before you book that you are well aware that there is no AC and that you will be climbing 6 floors every time.
