The best host I've never had. If there is a reason to love Barcelona, Montserrat is the main reason we love here, she was so kind and call my wife and me as her Kid, she called herself Mama. We came here for some wedding photography, the host, Mama, she ironed my shirt just wished me to have a better photo. Everyday we before went out, she will help us to figure out our outfit right, and kiss us before we leave. We love her so much even though she couldn't speak EN, but we still communicate through our body language and translator.
There are some notices you might need.
1. There had a tiny elevator, you still need bring your bag with few steps.
2. There is a cat, Tina. She is cute, we love her.
3. We have our own bathroom
4. No AC in the small room, but a fan totally can solve the problem. We did concern about that, the first day was hot, but after we had a fan, what left us were all good memories.

Generally, we love Spain because of Montserrat. Highly recommended. Five stars.
