Avoid.
They were recommended to me by another lawyer who didn't specialise in the area I needed. The experience was bizarre. They quoted me double the normal price (not unusual in Spain if they know you're not Spanish) and I politely declined their services. What followed I can only call bizarre.
They justified their price, but then within a few minutes said that they quoted me an outrageous price because they didn't want to do the job. Insults followed, including the suggestion that I was mentally ill and needed help. My psychologist and I had a good laugh over that one.
To say they are unprofessional is like saying that Microsoft do some software stuff.
