Lluis is a great host, communication was never a problem. The apartment is small but cozy, perfect for couples. We didn't even pay attention to the noise coming from the coffee shop downstairs, we actually liked the sound of voices coming from the street, maybe because we're a younger couple. Furniture and appliances are new, and you have everything you need for a comfortable stay. Lluis told us everything we needed to know when we first met him, and responded quickly through Whatsapp whenever we needed him. He also keeps detailed instructions, maps and everything you need in the apartment.
The apartment is located in a great place with 2 metro stations within 5 minutes walk. With all that said, I'm happy to recommend Lluis and his apartment to anyone visiting Barcelona, I will contact him for sure the next time I decide to visit.
