I stayed at 3rd Street for more than 6 weeks and highly recommend it. Simon was an excellent host and his apartment was quiet, clean and comfortable. Bouldin Creek is an old Austin neighborhood, close to the city center, with good public transportation, and there are good shops and restaurants within a few blocks of Simon's apartment. I worked during my stay so the apartment's large desk, comfortable desk chair and fast Internet were especially welcome. The apartment is a large--a very large--studio and nicely laid out, with good light, a serviceable kitchen and good storage. The only drawback that I noted were the large, uncovered--actually, partly, but not completely, covered--windows on the street side of the apartment. If that's not a bother for you--it wasn't for me--then you should definitely consider Simon's studio.
