I really enjoyed my stay at Hostal Ballesta in Madrid. One thing I really liked was the room with computers, almost like a small workspace. It was very handy and a great idea, as I have not really seen that in a hotel before.
My double room was very nice, spacious and comfortable, with a good desk and a smart TV, which made it easy to relax and also get things done. The location was also excellent, just a short walk from Gran Vía, with plenty of food places, bars, shops and metro links nearby.
The only thing I did not like was that the same workspace room also had a communal fridge and microwave for guests to store and heat food. I think this should ideally be in a separate room, as it takes away from the workspace feel.
Overall, a very good stay in a great location, with a nice room and helpful facilities.
