HORRIBLE EXPERIENCE!!!
Smart flats are not to be trusted. They are a third party company that operates outside the realms of Airbnb. I booked, paid and confirmed this apartment for 3 nights in Brussels, which I was then provided with check-in information, confirmation codes and receipts. Only to find out that when I arrived in Brussels that the apartment was double booked by smart flats and unavailable for me to occupy. Smart flats were slow to communicate this issue to me and offered no reassurance or another option despite their errors. I was left stranded in Brussels with no accommodation and place to stay. I would not recommend this service. They are unreliable, untrustworthy and pathetic in their ability to recognise an issue with their system and notify their client with appropriate advice and other solutions in considerable time.
