This is a lovely flat in a great location to base yourself in Barcelona. We were able to walk to both the beach and Park Guell and it was lovely having Sagrada Familia on the doorstep. It was probably a little smaller than I expected but this didn't really matter as for us it was just a place to sleep. There is a supermarket and cafe minutes away and a luggage storage (stowyourbags.com) a few blocks away if you need somewhere to put your bags after check out. And we felt safe walking around the streets at night.
The flat was super clean and both the bed and sofa bed were comfortable. There is a lift to the flat which is always a bonus. And the kitchen is fairly well equipped if you do want to eat meals there.
Jeronimo was very quick to reply to my messages and really helpful.
I would definitely recommend for 2 or 3 people. Enjoy!
