It's walkable, but a good uphill hike from the rail station - I'd suggest grabbing a mototaxi; there are plenty of them at the Inca Rail station when the trains come in, and as I recall cost about 5-7 sol from station to Parwa

I am obsessed with mosquitoes, they love me and I can’t stand being bit!!! With that said, I didn’t see any while staying at Parwa Guest House. However, we stayed 2 nights in late September when it was quite cold outside. So I’m not sure what the weather is going to be like in December.

You can contact Jorge directly and he can arrange taxi however we opted to go with Taxidatum as the rate was better comparing to other rates given to us ($37 one way). Great reliable service which we used several times while in Peru. Reserve car on their website and driver will be waiting for you holding your name by the meeting point specified in your confirmation. You can even chose option to tour Sacred Valley on the way from Cusco to Ollantaytambo (this option cost more, several options available) and kills 2 birds with one stone ;) You pay after you reach your destination. All info is on their website: clear and easy to book. I hope this helps :)
