Superb central location. Apartment has all that you would need. We only slept there as we spent all day exploring the city from very early in the morning to late at night.
6 flights of very steep stairs to climb if you feel up for the challenge but there is also a tiny lift in the building.
Michael was a great host and very helpful. Would recommend this apartment for two couples who are very comfortable with each other as the bathroom situation is a bit tricky ( having to pass through the bathroom to get to the bedroom, which has an opaque glass door). We had no issues but you do need to consider same.
I would have no hesitation in staying here again.
