First of all, Mourad is the best host there can be and he made my husband and I feel just like at home. He speaks English (and French), is very friendly, kind and helped us a lot in getting to know the city and the spanish lifestyle. Communication with him was excellent from the beginning: he responded to our booking in a few minutes and he even let us check-in earlier.
We had our own room and private bathroom (with everything you can need and access to the washing machine) and we shared the kitchen, living room and terrace (which has a beautiful view of Barcelona and the sea). There is also a little garden behind the house, with trees, vegetables and a barbeque.
The house is very charming and the neighborhood is quiet and safe, with lots of beautiful views. Even if you have to climb up the hill, there are elevators and electric ladders to help you. There are plenty of shops nearby and a bus stop in front of the house. The metro is just 5 minutes away, but you have to travel 20 minutes to the city center. Behind the house is a hill from which you can see both Barcelona and the cities next to it.
I wholeheartedly recommend this place. It was the first time we shared a place with someone else and it was a great experience.
