Superlujo Calle Preciados is in a great location, and very well outfitted - the place is modern, nice, and clean, and includes great technology (wifi, netflix, sonos). It's within a block or two of primary metro lines, with shopping and food opportunities literally right out the door. We were there during the Thanksgiving rush, and with the balcony overlooking the action it reminds of Mardi Gras...festive, music, etc.
The host was also most accommodating through arrival/travel troubles, a few questions about the place, etc. We got quick responses and felt supported throughout.
Ultimately a very nicely furnished apartment, well hosted, right in the middle of Madrid.
