We really enjoyed our 10 days.
The studio was indeed cozy. We found everything exactly as advertised. The pictures posted are a perfect representation.
WiFi was fast and reliable. Lots of hot water from the shower. Heating made it snugly warm (we were there in winter with up to -7°C).
Martha was nice and friendly and practical advise for us when we needed it.
We were allowed to leave the bags in the private hallway between checking out and going to the airport.

Would like to be back soon,
Cheers!
