Javier's place is very stylish and comfortable. The location was great - just a 10 minute walk from Piazza Duomo and from the Navgili district in Milan! Also, the surrounding areas are full of restaurants and there is a supermarket just 5 minutes away.
The reason it is not 5 stars are that it was a bit dusty, there was an ant problem, and the shower didn't drain properly. But I would recommend Javier's place as the pro's definitely outweigh the small issues.
