I think it's great we are able to leave constructive criticism, but i wanted to put a few things straight, for future Guests.
Firstly, the Apartment sleeps 4, but can sleep 5 as we have a single camp bed which can be put into one of the bedrooms - but the bedrooms are primarily set up for four people with double beds.
The Bathroom lock has now been fixed - thanks for making us aware of this from your review - no children will be locked in now!
The backdoor has been fixed, it is just a bit stiff and at no point have we said the Balcony leads onto the main road or a nicer view than the back of the building. It is just an outside space where you can either sit, smoke or hang washing outside of. Alternatively, we have the roof where it is open to all Guests and you can sit out there and enjoy the view from the front of the apartments.
