The location is excellent. The place is hard to find, with only a small sign at the shoulder level, and no street numbers. If your Google map misses the right location, good luck.
The hotel occupies the second floor in what was likely an apartment or an office. The space was extensively renovated, perhaps with some overkill. The shower is a few steps above the floor in the bathroom, with slippery marble floor and plenty of sharp angles. You can enjoy sound-and-light in a jacuzzi, though.
The staff was very friendly and responsive. Don't forget to let them know when you arrive, to let you in.
