This place is in a great location for walking around and seeing sights, close to Opera subway station and the Royal Palace and Royal Opera Theater. The Madrid City Tour bus can be picked up right around the corner, and you can buy tickets on board. Plaza Mayor is also quite close as well as Puerta del Sol - lots of activity at night there! The small elevator is so handy for luggage or just avoiding the stairs up to the unit. The unit is right on the street so there is some traffic noise in the front during the day and evening which occasionally drowns out the TV in the living room. There is air conditioning in the front sunny two rooms where you might be during the day, and oscillating fans available in each of the bedrooms at the back for sleeping at night when it's cooler. It's nice to have the wooden floor throughout, however, it does creak quite loudly as you walk past each bedroom so middle of the night trips might wake light sleepers. Also, it's quite worn around the dining table in the front room so be careful if not wearing shoes. There are three bathrooms - the front two have small showers, but only one with a shower curtain. The back large bathroom has a bidet, toilet, and jacuzzi with showerhead; no shower curtain but big enough to not splash out too much. (We did not try the jacuzzi or bidet function.) The kitchen was well-equipped with oil and condiments for cooking, and there was a dishwasher as well as clothes washer and dryer and detergent there which worked well for us. The kitchen also has a coffee machine for Nescafe cartridges (available in the nearby shops), however we were only there for 2 nights so did not bother buying a box of 16 cartridges. There are a good number of power outlets in each of the rooms so it was convenient for everyone to charge their various phones, laptops, etc. and the wifi was also useful to have. There were 6 of us for this stay - us, our two daughters, and grandparents, and everyone was quite happy to have such roomy and comfortable accommodations!
