The apartment is ok for 2. It is not close from downtown but the bus is definitely helping. There is as well another active area with shops and bars/restaurants within 10/15min walk (Antiguo). The closed parking place is definitely great.
If the place is not 100% clean, do not hesitate to ask Juan. I think his cleaning policy may affect sometimes the overall cleanliness of the place. Note that the sea view is very limited.
