Absolutely incredibly located apartment.
Very small though - I was on my own, and given the size of the facilities (small hot water service and bathroom) and the single shared bed/kitchen/living room and proximity to the sofa bed (a foot away from the main bed) I wouldn't have wanted to have to share with anyone other than a partner. Would've even been too small to share with my own kids.
The host seemed lovely, and the neighbours' piano provided a quaint ambient touch.
