Alberque la Poasada De Dorra Urraca.
I am now staying at this albergue. It is a bit open plan and certainly not the most appealing albergue I have seen, the sleeping accommadation is bunks, the mattresses are for emergency in summer, the kitchen is tiny with only a microwave, it´s an albergue
The pros of staying here are the thermal footbath and internet. I haven´t seen a computer since Ponte de Lima, not a working one anyway! Even I, a technophobe, was having withdrawal symptoms, and there is a cyber cafe in Caldas.
If you want peace, quiet and tranquility, and to carry food from Pontevedra, stay at Briallos, if you prefer towns and people stay in Caldas.
There is an Albergue at Redondela but I'm not sure whether there is anything that prohibits you staying before your first day's walk or indeed staying at the same Albergue again if you intend to return there during your camino.
There could be a credencial issue here as Redondela is within the 100kms and, I think, will not be able to issue a credencial, you would need a credencial to stay here.
Incidently the walk from Tui to O Poriño is one of the dreariest I have ever done, 7kms through industrial estates, worse than walking into Burgos. It does get better after that.
