Big and comfortable apartment, well maintained, clean and with good facilities. Great location - it takes just 3 minutes walking to get to Sagrada Familia and the nearest tube station. There are Lidl store and many small food stores around. Restaurants and coffee shops are also at a close walking distance.
The team is also great - polite and supportive. We had a problem with a leaking coffee pot in the kitchen and they reacted quickly replacing the whole coffee machine.
The only thing that we disliked about the apartment were the thin walls and lack of any soundproofing.
