The apartment was perfect. It is like a 8 minute walk to La Rambla. It is actually in a very non-turisty area and mostly full of locals. This is nice when you have had a full day doing tourist things around Barcelona. Lots of local shops and local bars/restaurants just across the street or behind the aprtment. Incredibly close to the Metro.

We called from the airport and someone met us at the apartment and we got 3 sets of keys which was great. No one lives here, it seems like it is only for renting out, which is fine, It feels more like a hotel than a personal apartment. There were plenty of towels & sheets for everyone. A fully equipped kitchen, washer/dryer and a little balcony on the 7th floor (with elevator).
Nicely laid out and all bedrooms had double beds (140 or 160 cm- not really sure). There are 2 bathrooms, one of them newly renovated. There was also a pull out couch, which we didn't need
It has very fast wifi.
We were 8 people and it never felt crowded. The living room has 2 sofas and a table which sat all 8 of us.
If you are a big group, this is where you should stay.
