Staying at David's was an absolute pleasure and I strongly recommend it for anyone visiting Barcelona.
First off, the location was great. It was slightly removed from the overly touristic area, but still a short walk (about 20 minutes) from La Rambla and about just as much to Montjuic. As a result, the area is safe and clean, and full of locals going about their daily business. Oh and did I mention the few great bakeries around? The area is also very accessible by public transit, but I walked around everywhere and was happy.
The apartment itself was very clean and very well prepared for my stay. It was as advertised, complete with access to a kitchen and a common area. The building has an elevator, so if you're coming with a suitcase, you have nothing to worry about. The one small downside was that it got a bit cold at night, but the bedroom was well stocked with an extra duvet which did the job.
As a host, I couldn't have asked more from David. He was very communicative and friendly, and he personally made sure that my stay was as pleasant as it could be. He was even kind enough to share some of his favourite places to eat in the area.
Overall, I definitely enjoyed my stay and would happily stay there again.
