We had a great stay in the apartment of Kris. The welcome by Kris was very nice, with good tips for nice restaurants in the neighbourhood. The apartment is clean and spacious and the building even has an elevator, which is nice when you have a heavy suitcase. The street may be noisy at night (in the weekend) when the weather is nice and the bar across the street is open, but if you want a quiet stay you should perhaps not stay in the middle of Barcelona. The underground station is a 4 minutes walk, just as a large supermarket (Bonpreu). Smaller supermarkets and bakeries are around the corner.
