Though Portugal is famous for its amazing hotels, hostels etc., this place is outstanding in the country. The old mill was restaurated in a very lovely way and it is very cozy and super beautiful. From the terrace, you can watch the sunset. The bed is big enough for two persons and very comfy. The hosts are super nice and very helpful. Since we arrrived quite late, they bought some groceries and fruit for us, so we had something for dinner. Of course, the communication was very easy. Our time in the mill passed way too fast!
Just some small facts that you should be aware of when booking: the mill is very cozy but also not too big and there is no real wardrope. If you are tall- be aware of your head- you are literally sleeping underneath the mill wheel. The kitchen is well-equiped, but a bit small as well and the cooking plates tend to overheat if you use both of them. So I would recommend using it only for minor dishes. But everything worked well and there was quite a good coffee machine :)
We had an amazing week at O Rominho and definately recommend staying there.
