A lovely flat right on the doorstep of Sagrada Familia. A huge bonus is Mercadona supermarket literally next door. All the touristy places within 30-45 min walk, we never used the transport.
The flat is equipped with everything one may need, including a few washing machine gel capsules and dishwasher tablets, and even 2 different coffee makers, a filter and a capsule one.
It can get a bit noisy, but we loved the chimes of the bells from Sagrada, and the whole vibe of living in Barcelona, if only for 6 nights.
