The rooms were moderate in size, neither too crampy nor spacious. Bathroom is clean and well equipped with geyser that worked without any hassle. A smallish wardrobe with hanger was present. No lift, so be wary of taking higher floors. The bed should be OK for two but a bit tight if you are traveling with a kid. (You can ask them to open up a separate bed out of the divan at some extra charge of course!)
There is rampant power cut at Lava. This place has generators in evening from 6 to 10 pm. After 10, they provide hurricanes (a type of kerosene lamp) for the rest of the night.
The hotel has a built in restaurant and a shop selling gift items as well chips, batteries, chocolates. The place is fairly well stocked with things, so good if you need to pick up some supplies for your onward journey.
Food is good. Try the momos (in one occasion they had put some junk stuff in them, though), egg noodles. Standard bong dishes like chicken curry and 'alu-posto' are also available, and quite good.
Owner is helpful and cooperative. As we were short on cash, he agreed to accept a part of the payment through online transfer. While checking out I mistakenly carried away the room key with me. He seemed to be irritated when he called me up, but was OK when I apologized and made sure that I send it back with the driver who was ferrying us.
