My son and I stayed 5 nights here. Uma welcomed us to the apartment and explained things plus there was comprehensive notes there. The place was spotless!
Yes, you do need to be good with stairs so no wonder she double checked. We were fine.
It is in a great location and has a wonderful atmosphere. The description of 'peculiar and cosy' is apt. Easy to walk everywhere but away from main tourist areas.
A thoughtful gift was left at Christmas and on our departure. My only disappointment was that I didn't really have the opportunity to maybe have a chat or two with Uma. She and her mother live close by.
We loved this place and it felt like our little home whilst there.
