Celma's place is a perfect place to stay in Madrid. Great neighborhood to be in, close enough to the main street of Calle Gran Via, but better yet is the surrounding streets of Malasaña. Everything you need is around this apartment; shopping, restaurants, cafes, groceries, etc.. As well as all the top attractions in Madrid, we walked everywhere and only took the metro when we were in a hurry.
Celma is a great host, fast at responding and goes out of the way to make your stay as comfortable as possible. We arrived in Madrid earlier than expected and she surprised us by getting us checked in sooner than planned. Better yet, she helped us out tremendously by ordering us a taxi for our early morning departure from Madrid.
Her apartment is very modern, quiet, clean and safe. Celma has made sure to include everyday essentials for travelers. I definitely recommend Celma's apartment to anyone traveling to Madrid.
