We stayed for 4 nights. The apartment was a good size and the views over the lake were really lovely, although a little obscured by the roof of the apartment in front. Easy walk into town (up hill on the way back but still easy).
I did notice a few things that could have been better - one of the kitchen stools had a rip in it, the kettle was dirty (brown water stains on the measure window), there was a little bit of mold in the ensuite shower and the range hood above the stove was a bit greasy. Nothing too major but a little disappointing, given the price tag.
Overall, we were really happy with the apartment.
