Thanks to a very friendly Thai family who picked us up from the side of the road after we were waiting for a a bus which was not coming and decided then to try to hitch-hike, we arrived in Mae Sot after a good 4 hours ride under the sun and the rain and against the wind, sitting on the back of their pick up van.
Somebody had told us about the Nº4 guesthouse so we decided to look for it and check it. We got a quite basic room with a mattress on the floor and a -very important- mosquito net, but for only 2 euro a night. Besides, the guest house was an old teak house with a lot of character and full of Thai artifacts and music instruments hand made by Mr. Om.
We came to Mae Sot with the idea of joining a trekking tour through the jungle to any hill tribe village of the area and Nº4 guesthouse had been one of the first companies arranging this kind of tours for “farangs” –western tourists in thai language-. Mr Om, owner of the guesthouse and former tour guide, seemed to be very professional although a little bit shy and taciturn person. After having red feedbacks of other travellers and a couple of different guidebooks rewiews, we decided to book a 4 day-3 night trekking with his company, starting the next morning travelling on a van to a southern town on the Tak province, Umphang, the closest town to the National Park of the Tee Lor Su Waterfall and close to the Burmese border.
