Perfect! I stayed 12 days in warm, sunny February.

Clara's mom met me at the apartment right on time. The studio is great, very private and well furnished, and in a nice building. I was able to do a lot of cooking in the kitchenette when I didn't feel like going out, and laundry too.

The neighborhood is wonderful, it's one of the nicest parts of Barcelona in my opinion, and feels very upscale. Only a few tourists happen upon it. You can do everything you need within a couple blocks, including multiple large supermarkets.

Extremely easy without a car. Metro is a easy walk, less than 10m, and there are several bus lines just outside the front door, and they all run every few minutes (except for the day the metro went on strike :P). Nowhere is far away. I explored many corners of the city and could always get home quickly, even late at night. I got in the habit of walking out the door 45 minutes before AVE trains at Sants, and still had time to grab espresso.
