A great apartment in an amazing location, close to lots of the sights and a few different Metro stations. Communication with the hosts was great and it was easy to check in and out.
The apartment had lots of light and equipment to cook our own meals.
As it is so central there is a lot of street noise at night so this is probably best avoided for light sleepers but we had been warned and brought ear plugs!
Overall it was a great base for our trip to Madrid and we are glad to have stayed here
