We have rented flats and cottages all over the world for over 25 years and Ilaia Madrid Palacio is one of the finest we have encountered. First of all, everything written in earlier reviews about how wonderful and helpful Marisa & Manuel are is completely true. They met us at the flat for an early check-in (very much appreciated), explained everything thoroughly, and checked in with us a couple of times during our stay to make sure all was well. I had one minor question a few days in, which was answered immediately. Second, the location of the flat is just fantastic, right in the middle of everything, but on a small, quiet street (filled with gorgeous flowering trees during our visit). There is a rather grand hotel across the street where taxis are always available, and a cafe with outdoor tables right below. No noise came through our windows, but it made for fun people-watching. Third, the flat itself is more than just beautiful, it is also super functional, which is so important. Everything worked perfectly: cook top & oven, clothes washer/dryer, shower/hot water, TV (complete with Netflix, which we really enjoyed), cool fire/humidifier, very comfortable bed, etc., etc. Everything was top quality and extremely well maintained. Finally, one other thing that set this rental apart was how wonderfully well-stocked it was. There was the lovely basket of provisions (cheese, wine, crackers, cookies, chocolates, milk, butter, jam, probably more that I'm forgetting) and also, besides salt & pepper, lots of herbs, olive oil, sherry & balsamic vinegar, etc. We love to shop markets and cook in new cities, so that was wonderful for us. If you are looking for a rental in Madrid absolutely plan your trip around the availability of this flat--you'll be very happy you did!
