The location doesn't get any better than this if you want an authentic experience in Barcelona. The studio is right on the corner of the main plaza in the Vila de Gracia neighborhood which is trendy and packed with local non-touristy restaurants, bars, and shops.
The studio itself was exactly as pictured. The design was convenient and had everything I needed for a comfortable 2-month stay. The wifi was quick and reliable for remote work.
I had very few problems/questions which were all minor and Ramon was always quick to respond and assist with all of them. My only complaint is that there was no air conditioning as advertised on the listing - only a fan. And it gets extremely hot in the studio during the peak of Barcelona summer.
