Really nice and very spacious apartment, clean and tastefully refurbished, quality fittings and fully equipped. Also located in the heart of an excellent location (Malasaña) literally a 3 minute walk from Metro Bilbao. Arthur was there to meet me, very pleasant and helpful, door-code entry simple to use. There is no TV monitor, but who stays at home when they're in Madrid? Good Wi-Fi connection too, I was there on business so needed it for work, no issues at all.
One small thing that might disturb light sleepers: it's on the 1st floor so a bit of noise can get in from the nearby main street, but it quietens down at night and the solid wooden inner shutters work fine when closed. I myself am a very light sleeper at times, but I wouldn't hesitate to book this place again for Madrid business trips.
