Is Luna and Simone convenient? + 2 day road trip itinerary after London sightseeing

Other than Greenwich it doesn't really seem like you're spending time in London itself so it doesn't make sense to stay in Luna Simone. To me, it makes sense to have the rental car as it will give you more freedom to go to all those places. On my first trip to London, my brother in law was working in England at the time so we had the use of his car. We had a similar itinerary as yours. He picked us up at Heathrow and we drove to Stonehenge and then stayed in a town called Bradford Upon Avon for 1 night. The next day, we went to Bath, Bleinheim Palace and Oxford. I know it sounds crazy but we were only able to do this because we had a car. We then stayed in Watford Junction for 2 nights and took the train back and forth to London from there. Now, I wouldn't recommend staying in Watford Junction if you were going into London for a couple of days as it's too far. I think you should look at a map and see what town is central to your Thursday and Friday sites and stay there and just drive to Heathrow on your departure day. Is that why you picked Astor? If so, that makes alot of sense to me. Have fun planning and bravo for driving on the left side of the road!

Where is Astor? I have never heard of it and neither has Google Maps!

Working backwards, assuming you are taking a transatlantic flight, you will need to be at Heathrow at 9.30 for check in, so drop the car back at 9.00 am. If you stayed Oxford, Salisbury or somewhere in between, you would have to leave by c7.00 to find your way back to Heathrow.

Stonehenge/Oxford are about 1.5 hours apart, so there isn't one location that shouts as an obvious overnight stop that doesn't involve lots of driving to and fro. You may want to look at Premier Inns to have two single night stays to avoid more driving.

Driving and parking in Windsor is hideous and I am well versed in driving in the UK! Parking in Oxford city centre is very expensive - they have bumped the price up to deter drivers. Park and rides will eat into your day.

I really don't know why you'd stay in London for this portion of the trip if you're going to all these places outside of London with a rental car. I can only imagine that driving a car in and out of London every day would be very taxing.

Thanks all and sorry for the points of confusion. I modified my original post, but just to clarify, we will be in central London Saturday - Wednesday and plan to visit all of the major sites. My Luna and Simone question is in regards to that time.

As far as the road trip goes, yes, I meant staying in the Ascot area instead of the mysterious "Astor."

That definitely makes more sense. I actually stayed at Luna Simone on my second visit to London and have been back a couple of times and haven't stayed there again. The hotel itself was fine- the room was small but clean, breakfast was good, bus 24 right outside the doorstep. The area was quiet and had restaurants close by and was a 10 minute walk from Victoria Station if you choose not to take bus 24. I just wanted to be closer to other sights so I stayed in Soho and then Russel Square areas next visits. London, however, has an excellent transportation system so it's very easy to catch a bus or the tube where you want to go. I'll be in London the exact week you will be there and this time I'm actually staying at a Premier Inn in Ealing. It's about a 30 minute tube ride into London but we'll only be in London 2 nights and my friend and I wanted separate rooms. Staying there made it possible for us to pay about $80 a night each.
