Amazing experience even if I got altitude sickness and didn't summit. Arrangements were great, the guide, porters and cooks were always smiling and always did their best. The 2 others I hiked with made it up, although one got sick and ended being brought down on a stretcher by the amazing porters and finished in the hospital for re-hydration. She was ok and proud of her accomplishment afterwards.
After the hike, we got to sit down, were dusted-off (oh, it gets dusty!) were given warm water to clean with, fed warm meals (a bit repetitive but tasty and of good quality). Our tents (and toilet, quite recommended to avoid smelly camp toilets) were set and we got to sleep quite well (extra air mattress suggested).
I was told the summit night was rough.
