I arrived at 10pm and was warmly greeted by the night security.
After checking me in and carrying my bag up to my room, he very kindly brought me a flask of hot water and a mug - as I'd asked.
It was no trouble for him and he asked if I wanted tea or coffee instead.
I had the hottest shower of my life - having to use the cold tap too!
(Hot water at the sink too.)
I had a very effective heater in the room, and with the comfortable mattress and pillow, and top quality bedding, I slept very well.
Breakfast is served from 7 - 9.
There was plenty of choice:
Cereals (cornflakes for gluten free).
Fresh fruit (kiwi, melon, watermelon, banana)
Fresh fruit juice (pineapple, papaya)
A variety of breads (all with gluten)
Tea, coffee, hot water.
Eggs cooked to order (fried, scrambled, ommlette)
The staff were all friendly and helpful.
There is a garden area to sit and relax.
It's a 10 minute walk to Plaza Sucre (Plaza san Pedro by the prison) where you can take a 3 hour walking tour for 20 Bolivianos.
Being out of the centre is more inconvenient than I'd have imagined. It's a lot of effort to pop back to the hotel after a day of sight-seeing and before eating dinner, and the tours won't collect you from here. So it's either a lot of hilly walking or taking taxis - or as I did, a combination of the two.
Taxi from the centre is 15-20 Bolivianos.
At $54 per night (which includes a 10% discount) I think it's overpriced.
