The Valentine Inn is a super basic hotel for those wanting a place to stay before, after or during a visit to Petra. The hotel is simple and popular with backpackers, though there were families (ours included) and older couples too. Evening food was available at a good price with barbeque and Jordanian salads served in a buffet format. One of the staff also played some Oud and sang during the dinner time, which was nice. The rooms aren't huge, and there are not a lot of sockets in the rooms, but it was comfortable for the purpose, and inexpensive. We brought our own travel cot for our young child, assuming (correctly) that they didn't have one available. Hot water is only available between 0500-0800 and 1700-2000, so be prepared for a couple shower! Wifi only really availalbe in the common areas downstairs. Paying for the rooms is cash only, so be ready with money. Breakfast was a simple Jordanian style spread of bread, cheese, labneh, hummus and vegetables, with tea and coffee available. There is a shuttle at 0700 and 0800 to the entrance to Petra, with pick ups in the evening too (the walk is a couple of km).
Overall, the stay was pleasant and hassle free, but this is a basic hotel/hostel to crash at relatively close to Petra.
