I've been staying in various places in Ruzafa neighbourhood for the past 6 years, a month or two at a time. Julia's apartment is the best apartment I've stayed in. It was clean, modern and comfortable in every aspect.
Even though it is located in the middle of this popular neighbourhood, the apartment is very quiet and I slept better than I have in a long time.
Thoroughly recommended!
Oh, and Julia is very attentive and responds very quickly to any questions!
