Plus(es):
a) Excellent location, close to shops and transportation. b) Very clean and pleasant accommodation. c) Access to a beautiful and large terrace with pleasant view. d) Good value. e) Stefano is extremely kind and available, with information, suggestions and help.
Minus(es) (but those were not bad surprises; the accommodation webpage states clearly and honestly the two following limitations):
a) No possibility of use of a kitchen, unfortunately not even availability of a kettle to prepare tea or coffee. b) The accommodation is at the top floor of a rather high building (which btw is nice for the aforementioned terrace) but... no elevator and lots of stairs (however, at check in, Stefano went promptly downstairs to help us with our luggage).
