My wife and three kids and I stayed in Jose's place for almost five weeks. We could not have asked for more. Jose's apartment is located just a 5 minute walk from a station on the L5 Metro. This line connects easily to tourist attractions (like Sagrada Familia) and also transfers easily to the airport line with just one transfer. A 30 minute trip on public transportation will get you to almost any place in the city.
The neighborhood is quiet and feels very safe. At the same time it is an easy to walk to buy groceries and fresh fruits, and anything else you would need (all within 50 meters of the apartment entrance). There are a few quiet outdoor restaurants very close to the apartment. Like I said, quiet but also has everything you need close by.
My wife and I were leading a service trip for University students and the living space was spacious enough for us to host everyone in the apartment for team meals (13 people including our three kids). The kitchen had all the amenities we needed.
The apartment was clean when we checked in and the three bedrooms accommodated our family of five easily (my wife and I, an 11 year old, 6 year old and 3 year old).
The air conditioner in the living room works well and helped to cool the apartment.
The building has two elevator which serviced our part of the building.
For families with kids, this will be a great place. There are a few parks within walking distance.
I recommend this apartment without reservation.
