Pleasant 2 bed apartment in Barcelona quite close to the Sagrada Familia and metro station, entry via key code system meant it wasn't a problem arriving late at night and no need for anyone to meet you at the building. There was a bit of noise from outside but to be fair you're in central Barcelona so to be expected somewhat. You need to pay the tourist tax before you arrive (3.30 euros per adult per night) and note there is a reception (open Mon-Fri) but it's not in the same building you enter for the apartment. There were some handy storage lockers to keep our luggage in as we had to check out by 11am but flight wasn't due till 9pm that night. Flat was very clean, a bit of wear and tear but overall fine for a few days stay. The metered taxi to the airport cost us about 38 euros (including the airport 4.30 euro surcharge).
