I'm sorry for the vote you left us.
I understand that you are disappointed for the problem we had but you did not notice the effort we made by finding another apartment with a terrace (perhaps better than what you had booked) so as not to leave you without accommodation the day before your arrival. I do not think it would have been easy to find another apartment in early September, in very high season.
I thought I had to help you because the problem was ours.
During your stay I asked you many times if I was happy and how it went, you always told me that you were happy to be there. Maybe a bit of sincerity helps solve some problems. if you complain only when you go away sincerely we can not do anything.
You've got the discount I promised you: do not pay the tourist tax.
The voucher for the taxi was for the offer of the first apartment that you refused because it was without a terrace.
Therefore do not say false because what has been promised has been given to you.
A tip: in the future, if you have problems during a stay, before leaving a negative comment maybe try to ask to solve the problem, you may have some pleasant surprises.
