Great:
location is unbeatable
value for money is great
easy check in-check out
cleanliness
design
little welcome compliments (coffee, cookies)
Pitfalls:
Poor internet (can be easily fixed by hosts)
Noise from the bars and cafes downstairs (hosts kindly provide earplugs, and this is smth you need to be ready to when you rent a flat in the city center)
Overall - definitely recommended!
