Petra was a warm and welcoming host! She gave us lots of information before we arrived.
Plus factors in her place: Location, right in the heart of the city (Jewish Quarter, Old Town). Walking distance from train station, groceries, and laundromat. The apartment itself was comfortable and as spacious as a hotel suite. Kitchen was complete with clean cooking and dining utensils, basic cooking oils and spices, towels. She had bath soaps and shampoos, dish- and house-cleaning utensils, detergents. Quiet at night (even it the city itself was buzzing with activity). Reliable wifi connection.
Minus factors, only for the information of other prospective guests. (We could adjust and adapt.). Toilet was some steps outside the apartment: a small closet along the open-air, public hallway. Even if clean, it had a bad odor wafting inside. Bathroom tub was next to the kitchen, no curtains, and had only a hand-held shower. Kitchen wood counter had some wear/tear, wood rot around the sink, from moisture - this may put off anyone particular about a clean appearance. Carpet though clean, had spots of stains.
