[Gocamino] question about guide services

[Randi W Buerlein/FS/VCU]

My daughter and I are planning to walk the last section of the Camino in 
September.   We would love to walk more but since we have a limited time 
that we can take off from work we decided to walk from Sarria to Santiago, 
flying in and out of Barcelona and staying 3-4 days in Barcelona before we 
fly back to the States.  We don't necessarily want to use a tourist 
service but maybe just some assistance with booking places to stay and 
perhaps luggage transfer.   I have looked into a service called Pilgrim 
Pathway and they seem to offer helpful assistance and accomodations in 
modest dwellings.
has anyone ever used this service who could provide some feedback?
Also, as far as starting the walk in Sarria,  any recommendations for 
getting there from Barcelona?
Thanks,
Randi
