We lived 7 months there.
The apartment is recently renovated, new and clean, there's everything you will need.
The host is very kind and receptive to all the questions you will ask. He never bothered us.
We wanted to extend our stay, but they have greatly raised the price, without letting us know. If you are a student, or you will come in Barcelona for an indefinite period, it will not be one of the most pleasant situations, when the price is changing every time.
The apartment is far from the city center, 30-40 minutes with metro.
There's no natural light in the house, that's a big discomfort, you don't know what's the weather outside.
And the biggest problem are the neighbors, they are so loud!!! They always make a big noise, no matter the time, argue or listen to loud music at 3/4 o'clock in the morning. The neighbors from above, move the wardrobe at 6am.
By the way, it was a good experience.
And thank you for having us.
