Advantages: good location, nice hosts, price (here not sure, when I came I found out about more low prices).
Disadvantages: no kitchen, no fridge, no microwave, so eat only in cafes. Very small room for me (it is previous children's room). The space of the room is cut in half because of the roof. Not simple for high peoples. I also didn't like the bathroom, here can only wash while sitting (but it is personally wish and habbit).
In general good option for 1-2 days , no more. For a longer stay better to overpay and rent an apartment separately.
Thanks for Stefano and Anna, I hope I didn't offend you with my review.
