My review, similar as those before me, is 'a wonderful, comfy, very clean apartment in great location!'
We (5 adults) stayed for over a week and the only issue we experienced was a single daily outage of electricity in the late afternoon or early evening. I was in contact with the hosts and they were very, very responsive. Odd that we had no issue in the morning when there was a ton of activity using electricity (heating, charging, washing, etc.). We stayed in the same neighborhood a couple of years ago and had no electrical issues. Although stressful, the issue resolved itself each time within 15 minutes or so. There was no final understanding of the exact issue. I didn't see any other review mentioning electrical issue so maybe it was related to construction going on down the road. It's a mystery.
I have to say though that we would all definitely stay here again! My daughter already wants to stay for a month to work remotely.
Sincerely
