I stayed in this apartment for 10 days in late February / early March 2018.
Good points: Great location, very clean, nicely equipped, excellent wifi, friendly and efficient communication with the host, efficient space and water heating.
Other points: This place doesn't claim to be big but I really must emphasize that it is very, very small. I'm a very small guy and it was hard for me to use the bathroom. Someone larger will be constantly banging into walls. I would recommend this place for a shorter stay and for someone who more or less only needs to sleep there. Although advertised as suitable for working, I didn't find the space allowed comfortable laptop work for more than an hour at most, so I worked from local cafes (which is fine, but should be clear to future guests).
Throughout my visit and as of March 8th when I left, the very steep section of road the building is on was totally ripped up for repaving. It was extremely difficult to leave and enter the building. I stumbled at night over stones and muddy patches. If you're planning on coming soon I would ask whether the work has been finished yet.
