Really a beautiful apartment, between the Rambla ( 2 minutes by walk) and the Barrio Gotico (5 minutes by walk).
The house is perfectly for a couple, but still good for 3 person, with a couch-bed very huge.
The stairs was the only problem, but it is a ancient palace therefor you have to expect that.
The check-in was incredible, they send you all the code for open the main door and the safebox outside the apartment door (with the key inside).
If I return in Barcelona, 99% I will book the same apartment.
