The apartment was not available when we arrived in Nizwa. I had called the landlord the day before to confirm the 3 rooms, I had reserved. I had asked for late check-out, as we wanted to hike in the mountains and hoped to take a shower in the late afternoon before heading back to Muscat.
Everything was confirmed to be told the next day that my confirmation through Expedia had been cancelled because Expedia is a bad company. We had to find a alternative accommodation, when is was already close to midnight.
