Last week I’ve spent 5 days in this hotel.
While the bed linen were showing some indication of excessive use the experience overall was positive:
1) fairly comfortable bed
2) fairly large room with no carpet (uncommon, but great to keep under control dust mites and related allergy)
3) fairly good food in the restaurant buffet
In several occasions the wi-fi bandwidth was insufficient for a voice-only Skype call, but a huge conference was ongoing hence is understandable even if it was unpleasant nonetheless.

The hotel is far from the city center (about 45 minutes by public transportation, 7€ round trip to plaza del Sol) and has a free shuttle bus to the airport every 30 minutes. Cab is about 20€ to the airport.

Given the price paid (90€/day with breakfast) it was a good deal.
