I stayed one month here. Location was great and very silent during nights, which is a big deal in Barcelona. The flat is located towards an inner yard, therefore it´s blocked from all the external noises from the streets. Apartment is clean, well-treated, host even offered cleaning service (free of charge) two times, once I accepted, when I wasn´t home.
Host was very dedicated and available if everything came up. He replaced the fridge to a new, when I noted that some parts were missing, also gave some additional furniture items, to make the place better while I´m there. He was nice and very solution oriented. Also, he was available easily, replied always almost within 30 minutes.
For home office it´s perfect, and you have all the things you need (supermarkets, restaurants, bus-metro, etc) nearby.
I can recommend this apartment!
