This is not in León but in the town of Astorga, 45 kms west, but a lovely place for a stopover. Newly rebuilt, spotlessly clean and centrally located, the Astur Plaza gave us a large "Junior Suite" with a double room and another room with a sofa bed where our two teenagers slept. They loved the hydromassage bath.
Staff were very friendly. Convenient for all the spots in Astorga.
The bar downstairs gave us regional cuisine at very reasonable prices. It was also full of locals as was the bustling square outside.
Get there early if you want a spot in the car park (paying extra) at busy times.

Our room overlooked the square and had a great view of the old town hall. One word of warning, for those who are light sleepers, ask for a room in the back of the hotel, since the town hall's bells do strike every 15mins until 1am and restart at 5am.

The hotel's rooms are large, well-appointed with large modern bathrooms. The staff is helpful as is the bar and breakfast staff. Its location on the square means that all of the city's sites are in easy walking distance as are most of the local restaurants.

A nice small hotel is this lovely city, a good place to stop.

New hotel and geared for international travellers ( they speak English). Lovely large rooms, very clean, cheap minibar and the poshest 3 star hotel we stayed in. Underground garage. The hotel overlooks a square with church , and more importantly a few bars and restaurants. This is not the main square in Astorga but we found it had much more life and many more local people. Breakfast was good. Free internet access in lounge area which for us was a boon.
