We - my wife, my 10 months old son and I - stayed in the apartment for 2 nights and had a great time!
Oriol is a welcoming host and takes his time to make sure that you know everything you need. He even gave us a city and metro map and provided tips on the map where to go in the areas we wanted to visit. A great start!
Also a baby crib and blankets where arranged for our son. The apartment is very clean and well organized. There even is a washing machine so that you can do your laundry.
Not to forget is the perfect location! Very close to sagrada familia, but for our standards also on walking distance of the city center (+/- 30 minutes walking with a baby in a stroller) and other nice areas like Gracia. In case you do not like an urban hike the public transport (bus/metro) is also close to the appartment.
It was a pleasure to stay in Oriol's apartment, we would absolutely recommend staying here!
