I went to Nepal for two weeks to work in a hospital in Kathmandu. I went through the Global Crossroads program, which appears to stem from the same base as this one. Overall I had a great experience. Arriving was a little sketchy, as we were picked up late at night at the airport by a man who was a stranger to us. Quickly our luggage was taken by another man and set into the car for us, and he then asked for payment, which I wasn't happy about. I learned then that he wasn't a part of the program, I'm just advising you to be wary of that. We went to a very nice hostel near the center of Kathmandu, just a short walk away from the hospital we worked at. The hostel held around 10 volunteers, but it was never completely full during our stay. It was also where the organization takes place, so if I had any questions or concerns, I could just walk to their area of the house and ask. The hostel had kids and families in it, two sisters were in charge of all the food, and were very accepting and accommodating of my diet restrictions.
I'm not sure of the official title, but let's call her our coordinator. Pratima was essential in helping us figure out a new culture, and she gave us a crash course into what to expect, and how to react in different situations, which was very helpful.
We had several kinks along the way, such as loosing our luggage, and injuries as well, and Pratima was accommodating to all of it, calling the airport everyday to locate the luggage. When we needed to find a place she told us where to go, and acted as a translator when needed. Also, the organization created a little 'tour' type thing for us and a few others staying in the hostel to see some of the well-known temples and such. We were also given a little tour of all the places we might need to go while we were in the area, like the ATM, the store, our work place, etc. so that we didn't go in blind.
The reason this has 9 stars out of 10 was because there was a little hassle with the money which was a little suspicious to me, but understandable because I think they work from both the US and Nepal, it was just unclear who I had to pay and how much.
Overall I had a great experience through this program, and would recommend it. Just be aware of working out the payments very clear. Everyone was helpful and accommodating, I plan on returning there later in life!
