Thank you for the lovely apartment, it's a great and complete apartment. Great neighborhood.
I'd like to suggest to keep the bedrooms cleaner, there were dust under the beds and under the books. The blackouts that rolled down outside of the windows were black of pure dirt, there were big spider webs outside the windows as well, clearly they were there for too long. Our kids suffered a lot , cause they were allergic. There is no excuse for not keeping bedroons clean. For this very specific reason I'd not rent it again nor recomend it.
Other suggestion: since we had almost 40oC of temperature that week, and the place is not prepared for heat (there were nor air conditioner neither fans), bedroons heated a lot. Therefore we had to buy for our expenses two fans, each for EU$30,00. We let them at the apartment. I'd ask for a refund for them, maybe 50% of the value. It would be fair.
As for the check in, once we land it for an international flight we had to pass for security, immigration control, baggage claim, and a lot of traffic through the city. We communicate our arrival time weeks before the flight and since you were the professional dealing with tourism everyday you should know of all this. The lady that received us, Ursula, would not wait for us, telling me that I was late. I told her that it was not my falt and we had children so she had to wait for us. Then she waited, but she behave as if she was making us a great favor and not just her job.
And for last, in the second or third night the owner of the apartment entered with her own keys and was surpised that we're there. I told her that we're renting it by Airbn'b and asked if the agency didn't told her. She told us that she was not told about it. But she was very nice and understandable.
So , these are suggestions to improve your work.
Best regards.
