I'll be recommending The Social Hub to everyone!
All is excellent; the location, room, price, staff, facilities (rooftop pool, gym, free washing machine and dryers - which is needed on a long trip!), and the general vibe of the hotel is so positive.
My sister and I stayed at both The Social Hub in San Sebastian and in Madrid while visiting Spain this year and both exceeded our expectations.
They even have fantastic looking meeting rooms, quite individual work spaces. This would be an ideal hotel to stay at if you have to work remotely while away.
