Initial access was easy using instructions complete with photos. However, the spiral staircase (no elevator, be warned!) had narrow, worn out wooden steps and was poorly lit (lights go out automatically on short timer). Final door to get access had a malfunctioning NUKI electronic lock. We wasted no less than 5 minutes each time we left the room. We told the owner about this issue, but his response was usually delayed.
Upon entering, we were greeted by a nasty smell; the odor was definitely strongest in the shower. Otherwise, the room was clean, if a bit cluttered by too many stools.
Finally, the rooms are very small (sidestepping was necessary with any open luggage). We are currently in another AirBnB 400 meters away with much more room (2 bedrooms) for a better price!!
Recommend for only 2 travelers, despite listing showing 4.
