I'm British and prior to visiting here thought it would be the Windsor of Spain. Royalty wise it is, and proximity to the Capital. The analogy breaks down though Escorial is more homely and relaxed whilst it has a tourist element it doesn't dominate unlike Windsor.
The flat is in my estimation in quite a classy area tree filled area in walking distance of the monastery. I was going to say easy walking, but the slope the whole town is on means that in truth there is no easy walking anywhere in Escorial. That adds to the character of the place.
The flat is on the top floor of the block so more climbing it has a view which is good, but if it was a storey higher would be spectacular. Flat is continental in sense of large lounge diner small kitchen. My party was five person family and I would say a good size flat overall.
I went in July Very hot! No AC so the full Spanish experience. Glad I'd booked here rather than anywhere lower such as Madrid.More
