thanks for your feedback! Of course the Sofa IS a convertible sofa bed and it has a size of approx 140 cm to 210 cm.
The check In process was clearly sent to you, as you can read in the messages we shared, i kindly asked you to tell me an exact time of arrival to ensure that someone will be there for your convenience, but i received no clear response from you unfortunately. Regarding language problems, I was/am always available to respnd to questions via phone or message and of course the phone number which is provided on airbnb is a valid, working phone number which i am using everydayy, maybe your phone was not working at this time, which i am sorry for.
nevertheless i hope you enjoyed your stay.
