Safety issue with balcony door not closing, and very accessible if someone wanted to intrude.
The sofa bed downstairs, given won't be comfortable as it's a sofabed, however a direct street lamp shines into the living room at night, she can't afford curtains after all that you pay for the place.
There's no negotiating, as we wanted to cut our trip short, due to uncomfortable beds as well, however the response was very curt with 'Theres no way' as the first line, rather than being considerate of our issues. Definitely not worth the price, it's a rip off just because of the location.
