We had an amazing stay in the apartment with my boyfriend, there are many great restaurants around and walking all the way to different Ramblas through streets of Barcelona is really nice. The apartment is a bit bigger than it looks like on pictures and has everything you need (fridge, washing maschine, dryer...). Bathroom is a bit small and has no surfaces to put stuff on them but that is not too bad. Balcony is also not that big but enough to drink coffe outside. The walls are quite thin but we didn't hear neighbours much and surroundings was quiet and calm. There is a shop on the other side of street where you can buy everything you need. They charged us extra 70eur for tourist tax. We got informed about this expense after booking the apartment.
But we paid that and all in all were happy with staying in the apartment.
