We had a fantastic stay in Gracia. The apartment was in great location less than 5 minutes to the Metro station Joanic which takes you right into the city with no stops. We love Gracia and the apartment has good access to the whole area. The front bedroom is on the main road but we always take ear plugs whenever we travel to a city and it was not a problem. Barcelona is such a noisy, bustling city so we expect road noise wherever we stay! The apartment was really clean, light and the bedrooms were surprisingly spacious. Perfect for the 4 of us!
