Everything was great except.....we couldn't get a sim card because all the stores were closed. Without a sim card, we couldn't open the front door. After several attempts another guest opened the door for us.
The place itself was immaculate. Using a shared washroom and kitchen was not an issue as there was more than washroom. I never saw anyone else on the kitchen. It was actually nice talking to a few other guests. The place was exactly like the pictures. Great location as it was close to Madrid central and also unique restaurants a two minute walk away.
