Our stay at Villa Diletta was great. It was clean, it looked exactly like in the pictures (the bed was actually bigger than I expected), and it was absolutely EXCELLENT value for money. If I ever go back to Luxor, I would stay there again.
It was quite close, maybe 6-8 minutes walking to the public ferry (1 EGP, no haggling necessary). Also close to some stores (near the ferry stop). I think one of the stores is called something like "Yura" but I can't remember. Anyway, beside that store, you can get falafels there in the morning (2 EGP) -- ask Mohamed.
It's located on the west bank, in a quiet area (can hear mosque at night, but it's hard to find a place where you can't!). The little garden in the front is very nice, we sat there in the evenings to read/talk.There was a lot of hassling on the way to/from the ferry ("taxi?"/"want to come into my restaurant?" and so on), have to ignore (or develop your own tactic to deal with it).
Wifi is kind of slow but works decently. Free laundry, buy your own detergent. You can hang your clothes on this rack outside. Water pressure was good. Bathroom was clean, and very large. A few mosquitoes. Didn't use air conditioner so can't comment on that. Kitchen had cutlery/some appliances you could use. Never watched the TV.
Mohamed is willing to help you with whatever you need, we had dinner with his family one night and the food was absolutely delicious. He is really friendly and his English is very good (we never met Roberta).
We asked to be picked up from the airport, which I would highly recommend. We also booked a private taxi driver through Roberta to visit the valley of the kings and some other temples. This turned out to be quite expensive. The driver is knowledgeable and reliable, and if you have the budget for this, I would recommend him (also named Mohamed). But if you want to travel more cheaply, there are other options (other taxi drivers, not sure about their reliability since we never took one, or mini buses, which may put off some people -- 1-2 EGP and you just get on, the door to the van may still be open, and hope it will go the right way. Just get off if it veers off course. There is a depot right beside the ferry on the west bank. We took it once, back to the depot. It was fine. Probably a bit weird for the Egyptians on board.)
So all in all, I would highly recommend Villa Diletta to anyone. It was excellent.
(And in case you're wondering, we didn't really feel unsafe (regarding any uprisings). There was a lot of hassling because of the lack of tourists, but the tourist police apparently has a lot of power there).
