My friends and I had a pleasant stay. Damien is a great host. Checking in was super easy and the lady at the reception was super nice and flexible and let us keep our luggage in the locker upon checkout.
Pros:
Clean apartment and comfortable beds
Free Coffee+Pastry in the morning for our entire stay in the downstairs cafe + Water and beverage provided in the fridge. Those are great touches!
Decent living room
Amenities all available
Clean towels + Soap/Shampoo/conditioner were provided
Great location
Cons
The only thing I can think of is that the main bedroom was noisy at night as it overlooks the main street. Not an issue with the apartment itself considering the location and busy night life in Barcelona. Maybe just upgrade the windows to be soundproof for light-sleepers
