I stayed 5 nights at Sercotel Suites Viena in Madrid. Unfortunately the wheather was terrible, the city was flooded and our spacious balcony / terrace ( 4 chairs+ table, 20 square meters) remained just a reminder that the Madrid has good wheather too...
We paid an extra 20 euro's per night to upgrade to a suite since they didn't offer regular rooms with a balcony. The suite is a good size with plenty of storage space. The bathroom is small (1 basin, bath and wc) but clean. A kitchenette in the sitting area with a small fridge/freezer, microwave and 2 burners. You will need assistance from the receptionist to get kitchen utensils (a pot to boil water for tea f.i.) and to switch on the main plug for the kitchen appliances. You'll be able to make breakfast and nescafé, but with just 1 pan, don't expect to do much cooking. The staff is helpful and friendly. They provided umbrellas (much needed) and wheather reports (bad news).
The airconditioning/heating, the laminate floor, the blackout curtains, the good-sized bed and comfortable modern furniture made our stay a very comfortable one (despite the endless rainstorms). I would recommend this hotel to anyone for any purpose: business (good desk and free wifi), family (kitchenette= ideal with children, quiet and safe location) or citybreak (near royal palace and bike rental next door).

The hotel is very well located in a quiet street, close to Plaza de Espana & Ventura Rodriguez metro stations. The staff are very friendly and helpful, with excellent service from housekeeping.
We did not take breakfast in the hotel but used the Cafe Viena (same owners), just up the road.

The room was good, except for the design of the shower area, which really needs something to stop the water going all over the floor!
Although you can ask for crockery, cutlery, etc., which was brought quickly and willingly, the kitchen area is not really very suitable for self-catering. If you want to make coffee, suggest you bring your own coffee jug and kettle!
