Joan's place is a great place to stay in Barcelona. It's perfect for 2 with a bedroom, kitchen, living/dining room and bathroom. The location is fantastic in a residential (i.e. non-touristy) neighborhood but not far from Barcelona's main attractions. Tons of local bars, restaurants and grocery stores nearby. Buses 1 block away and the metro 4-5 blocks away.
It's on the 2nd floor (3rd floor US) with a narrow staircase and no elevator. If you have large suitcases (>26") the stairs may be a struggle. Air conditioner and wifi were strong.
We really enjoyed being in a more local neighborhood than with hordes of tourists. We enjoyed wandering through Gracia and stopping at local cafes and restaurants. Would definitely recommend Joan's place when in Barcelona.
