We had a great stay at Gretel's place! Gretel is a great host, she always responded very quickly and was very accommodating. Her place is extremely clean and very spacious with wonderful personal touches. The kitchen was equipped perfectly well for ua to cook some nice meals and there was even some milk and orange juice in the fridge for breakfast - The welcome beer and shortbread was a wonderful surprise as well.
It is a bit of a walk to the city centre (~20 minutes) but with lots of interesting things and great restaurants along the way and if you don't feel like walking still, there's a bus stop just 2 minutes from the flat. The flat is located in a very quiet street, so getting a good night's sleep was no problem, especially since the bed is very comfortable as well.
Only complaint would be that the WiFi was very weak/slow most of the time, but that's really a minor thing.
Can't recommend this place enough, would come back for sure!
