I searched for your place (for 1 and 2 persons) using various filters (price range, neighborhood, etc) and your place came up.
If your inquiries and bookings have slowed or stopped, it's probably just due to things such as the large number of competive listings in your city (lots of people don't use filters, or use too few), or just a temporary slowdown in general. Our own listing is extremely popular and stays 90-100% booked usually 1-2 months in advance. But right now we haven't had a single inquiry for 2 weeks. Nothing unusual; next week we might suddenly get 3 inquiries per day and I'll be annoyed by my phone beeping all the time. 🙂
One thing I suggest is that you lower your base rate. When I click around on your calendar I see that you've set lower rates (some of them a *lot* lower) for most days going out 2 months. A lower base rate, reflecting what you're really charging most of the time, would help your listing show up in searches when people filter for a lower price range. For example, your place currently won't come up at all if someone searches in a range under $200.
