Maria is the greatest host ever! She is very welcoming and enthousiast about Barcelona and will give you a lot of great tips on what to do, where to eat etc...
The appartment is great, 3 very nice bedrooms, 2 very clean bathrooms, a great terrace (excellent for quiet breakfast and an evening drink). It is located next to Parc Joan Miro, which is an excellent starting point for many visits in Barcelona, direct access to metro and great to start long city walks.
