This is a great apartment, we stayed here for 4 weeks and really enjoyed our stay. It's very comfortable, quiet, modern and well equipped for a long stay, and much more spacious than in the photos. Cooking here was a pleasure, the kitchen has a great cooker and oven, big fridge/freezer, microwave, toaster and plenty of cutlery, plates, cups etc. The shower is great, there was always hot water. In case it gets chilly, there's a very efficient, autonomous gas heating in the flat. The internet connection was really good and we had no issues working from there.
The location of the flat is very convenient, there are plenty of cafes and restaurants within a short walking distance, and a supermarket basically downstairs. There are also metro and tram stops closeby, but you can easily walk to most places in the centre from here.
We didn't get a chance to meet Jenny, but her mum who gave us the keys and showed us the flat (and kindly let us check in earlier!) was very lovely. We'd happily stay here again!
