The Key Inn was a lovely, centrally located, and spacious apartment near the Gothic quarter in Barcelona. It may be a bit small for 12 people, but the 4 of us had a great time and more than enough space. The streets aren’t very noisy at night in thsibort if the city, but at the time we stayed, there was construction going on that woke us up very early in the morning. The apartment was very clean too. Overall, we enjoyed staying here very much.
