BUS OR TAXI? (Tirana)

Hello everybody :-)
I will be in Tirana on the 04th of October.
I am wondering if I can feel safe travelling downtown by bus or u suggest better the taxi - what company please?
I am supposed to land at 08.40pm. I hope there will still be buses running to the centre!
The following morning I need to travel to Sarande but I am finding very tricky to search for information. How can I reach Sarande by bus from Tirana?
Thank u in advance for your help!!!!
