We had an enjoyable stay at this minimal apartment. Klara bought us 2 beers and gave us a list of suggestions to visit during your stay which is quite helpful.
The shower lasts for only 5 mins on full blast, then you have to wait for the tank to fill back up to use it again (about 20mins). We were not warned about this before arriving! Although we managed a work around it was a bit frustrating, as we weren't expecting it. Thought it was necessary to inform people on this, as it wasn't mentioned on the listing and I haven't seen anyone else mention it here either!
Despite WIFI displaying 20mb/s download speeds, it was very weak (possibly due to the router being old?), so streaming larger data like sending pictures and videos to friends via Whatsapp or playing media from Spotify or Youtube was impossible. Bit of a first-world problem, but worth noting.
Besides these things the flat was lovely, would recommend for people on a budget, but the above notes need to be added to the listing to inform future potential visitors.
