The apartment was perfectly located in the middle of Madrid. Plaza Mayor is very close. The apartment was nicely decorated and clean. There was an issue with the wifi when we arrived but when we contacted Daniel, he addressed the issue and was resolved right away. Daniel was always available if we needed something.
The only real issue was that there were not (or at least we didn't find) towels or toilet paper for us which was disappointing after you are paying but other than, it was a nice stay.
We'd stay there again.
