This place has great location - just couple minutes walk from metro and Sagrada Familia, 25 minutes on foot to Plaça de Catalunya.
But...
1) small bedroom has twin bunk beds, not two separate twin beds. So not friendly for elderly people
2) bedrooms don't have window to the street or yard. Instead they face utility shaft with pipes. So you will hear when your neighbors upstairs flush toilets or take shower
3) Ugh, bathroom! Its hard to enter and maneuver. Once you open door you will have to step in shower cabin, then close door and only after that you will be able to use toilet. Big size guests might have problems.
4) taxes. On arrival Host asked "tourists tax" in cash separately from Bill you pay via Airbnb
Overall, it's a nice place. But don't expect "cozy home feeling" - this is commercial for-rent apartment with IKEA furniture.
