I stayed in this 2 storey loft for 3 nights this week and I loved it! It looks exactly like the pictures and everything is clean, organized and even the soap/shampoo are all labelled in English. Everything is supplied and Enric was there to greet me, show me around the apartment and give me some friendly advice on where to eat. The big unexpected perk was that they provide a cellphone for you to use which has Internet so that you don't have to use your own roaming data.
Of course, the main attraction is the view of the Sagrada Familia from both the skylight above the large bed and from the private balcony. It's absolutely perfect and an amazing thing to see first thing in the morning and last thing at night. The location is also spot on - literally 2 minutes from the Sagrada Familia metro station and across the street from the church itself. The apartment is located in a quiet (but not sketchy) side road that has a great fresh seafood restaurant and a wine store. The entire neighbourhood is about as safe as I imagine Barcelona can be, and I travelled by myself.
I truly love this apartment and would stay here again in a heartbeat. And yes, there's no elevator so you're going to have to walk up and down the stairs but seriously, it's Europe so walking is pretty much par for the course.
