Sorry to hear you are having a difficult time. In my personal experience, February is the slowest time of the year here in London, but I am still getting enough bookings. Two of my rooms are fully booked this month and the other is empty for one week because I blocked it as I am away on those dates.
I don't think Brexit is a factor. I haven't noticed any decline in bookings since the whole fiasco starting happening, but I have had several guests mention they chose to come to London because it became more affordable after the referendum.
Yes, there is a lot of competition in London so you have to offer something that keeps you ahead of the rest. Convenient location is key but also competitive pricing. I refuse to lower my prices but during slower periods, I'm not upping them either, as I might do in mid-Summer or around Christmas/New Year. However, my listings are probably under priced already (mainly to attract long-term guests, whom I prefer), which I am sure is a big factor in how popular they are.
Another thing is that you have to offer something different to the competition. I hope you don't take offence because your listings look lovely, super clean, modern and well maintained and you have great reviews, but most of my guests book because my place is a bit different or special. Not everyone is looking for that of course - some people want clean, modern, well maintained and nothing else - but there are enough people out there looking for something a bit different that it means I never worry about bookings anymore.
Sorry, I'm not trying to be smug as I also get nervous when things are starting to look a bit quiet, as I have a mortgage and bills to pay after all, but those nerves always turn out to be unfounded as the bookings do eventually come in, even if they are more last minute than usual.
Yes, this month, one of my rooms was looking quiet quite late in the day. The current guest indicated that she wanted to stay another month but faffed around because she thought no one else was going to book the room (I did warn her that this was unlikely). So, she missed out because all the dates she wanted have now been snapped up.
So, not to ramble on anymore, I would suggest you maybe think about a USP. What can you offer that other listings in your area (and beyond) don't?
