My flight from Diri Dawa to Addis Ababa is today at 16:00. I was going to take the public minibus from Winta Hotel in Harar to the airport in Diri Dawa in the morning but I ran into a Japanese tourist who had a private minibus. I paid him 20 USD to share his ride to the airport, about an hour away.
We left at 09:00 and got to the airport in record time at 10:00. I thought about changing my flight from 16:00 to 12:30 but there was a huge line at the counter so I didn't bother. They would have probably wanted me to pay more for the earlier flight since it was more expensive than my ticket.
The flight to Addis Ababa was smooth and fast. I walked out of the airport and across a big street to find the Zenbaba Guest House. It was about a 15 minute walk. Of course, the hotel wasn't at the map location specified on Booking.com. I had to find WiFi and then call the hotel to find out where it really was. They sent me a WhatsApp with the real map location and I found it easily.
