We stayed for a week at the Ma Bass guesthouse. Our room was a great price, clean and comfortable with air conditioning (note: only 1/11 rooms has it), sky TV and en suite. Ma Bass was a wonderful hostess, who treated us like her grandchildren- we felt at home away from home. She helped us out in many different ways including arranging guides for hikes, booking taxis, recommending restaurants and even made us a big lunch when we ran into money problems!
I would definitely recommend this guesthouse for it's friendly atmosphere, excellent central location and good value comfortable rooms.
