Everything from the booking of the safari trip to our departure was excellent.
No problems with communication via email, we were reassured we'd be picked up from the airport on our arrival, and accommodation both after and before safari was included. Arusha Tourist Inn Hotel, in which we stayed, was very conveniently located and comfortable.
They asked if we could start our trip one day earlier than planned, which was fine by us, except that day we needed to book bus tickets from Arusha to Dar for after safari, so Geofrey kindly agreed to do it for us, and for us a great price too!
On the morning before the safari we were picked up by our driver, Daniel, who did an excellent job at making sure the whole trip was an enjoyable experience. He was able to spot animals from hundreds of meters away (spotted two mating rhinos!) and was very knowledgeable. Cracked a few jokes too, so overall, great guy!
As to the accommodation, we were pleasantly surprised that the at the Sunbright Campsite we got a tent with an actual bed! It was very comfortable and clean. The other two nights we spent at Seronera Campsite in Serengeti, where you could hear the hyenas walking around at night (surreal experience!), and Ngorongoro Campsite where we were greeted by several maribu storks - which was both scary and exciting!
I cannot recommend a safari trip enough. Being in Tanzania and not experiencing the nature would be just wrong! And Meru Slopes ensured that our experience was unforgettable.
