The easiest option is to use the free car park opposite the pharmacy on Av. Isidor Machabich and walk approximately 5 minutes up the steps next to matthis shop. At the top of the steps, keep on walking and take your first available left to the studio on Calle Estrella.
There is also on street parking in the streets surrounding the studio (you will need to buy a parking ticket to park in any blue bays unless you are parking during siesta time which is free). However it can be difficult to find a parking space in these areas especially in the summer so we would highly recommend to go straight for the big car park and short walk.
