First of all - in all fairness, I wish we were told that one person is disabled in your group.
When you enquire about the property, it is advertised as a split level home - and all split level homes have stairs, due to that, I would personally advise this property is perhaps not suitable, as it can challenging to a disabled person. Regarding distances ( Now changed again ), my mistake as for most people this is considered very close, but for a disabled person a walk of 400-500M would be a challenge, yes. Please forward our apology to your Mother, we did not know about any special needs. And for beds etc, I do take full blame, yes 2 beds are double beds, honest mistake of me I was not aware, for that my apologies! However, sleeping on the floor sound very dramatic! The lounge was not considered? From personal experience it is pretty comfy as an alternative!
We are not desperate people, we have only been involved with Airbnb for 1 month approx. so we are learning as well, but we do take all on-board - bad or good, nevertheless we always will continually improve the facilities, as just finished changing the pool with new pump and fresh water system - less chemicals! This was completed after your stay. We will forever continue to make the stay comfortable for all our guest to the best as possible, including services or purchases, more useful equipment etc.
