In our apartment we have with Airbnb we have two rooms, each with two single beds of 90 x 200 cm. We have the possibility to join the beds perfectly well and anchor them, put a large cover and thus have a king sized bed in each room of 180 x 200 cm. We have included this in the description of the ad, so there is no doubt. Currently, in the ad it is required to indicate a single number in relation to the number of beds, so have put 4 beds, in an apartment for 4 people, but this does not reflect reality well. To solve this we propose three possible solutions:
1. Do not necessarily indicate the number of beds. In this case, the interested party would look at the description of the advertisement. It has been this way until recently and it has worked well.
2. Indicate, in our case, between 2 and 4 beds.
3. Have the possibility to indicate: 4 single beds, or 1 double bed and 2 single beds or 2 double beds.
The most accurate would be the third option, the first one the most simple one.
