Vivian and her husband are excellent hosts. Vivian was away but made sure I had what I needed to make my stay comfortable. Her husband Kenneth was a perfect combination of welcoming and unintrusive. The flat is very well cared for and in an excellent location away from the bustle of the city.
The flat is 25 min tram from the center but this means that it is virtually silent in the morning and sleeping in after a late night was luxurious. It is along the 5 tram which is a primary line running pretty much at all hours and the one very late night I got an uber and it was worth it.
I highly recommend for a short stay for one. It might be a bit crowded with two if you are staying more than a night or two. Don't expect to cook in the kitchen, though you can leave things in the fridge. Overall an excellent experience.
