- Not advised.
The city of Siem Reap is best known as being the site of the Angkor Wat temple complex, and as such, there certainly is no need to get a hire car within the city itself. Most of the major places to stay are within a short walk from Angkor Wat, and plenty of local buses, minibuses and taxis are available.
For any additional day excursions out from Siem Reap, then we would recommend using local guided tours.
