Camino Inglés information

Not done both in one trip but you can walk from Bruma to Meson Do Vento (off the Camino by about 1.5km) and catch the bus back to Coruna. You can then walk Coruna to Bruma in one stage (about 30-32 km) or break the stage at the Albergue in Sergude.

Hotel Almendra in Ferrol is good and very good value for money.

Several buses a day from Santiago to Ferrol. Airport bus goes to Santiago bus station from where the Ferrol bus leaves. See http://www.monbus.es/en/routes-points-of-sale/155/travel-santiago-de-compostela-ferrol/ and the Almendra is about 500m from bus station.

PR Hortas is a small, nice hotel, well placed for Cathedral and old town and reasonably priced. I'm sure will get more and equally valid recommendations.

There's a bus from Santiago to Ferrol. I think you can catch it from the square (forgot the Praza name) just outside the old town or from the bus station which is what I did. Lots of decent looking places to stay in Ferrol. I picked one at random from the CSJ guide/booking.com Hotel El Suizo and liked it. It's worth having a good wander around Ferrol the day/afternoon before you start walking.
I really liked the towns and cities on this camino. They're all worth a wander. Betanzos has lovely churches and lots of restaurants. A lovely lady at the museum let me in for a look when they should probably have been closing up for the day after we had a good chat. I also stayed in PR O Meson Novo in Meson do Vento which many have recommended.
I like Pousadas de Compostela Hotel San Clemente in Santiago but it's not always cheap. It's worth checking for deals.
