I've been here for 5 days, apartment (high ceiling) is perfect for 2 persons (shared bed and a couch), huge living room. Kitchen is shared (this time with Illia's mom) as is fridge (huge).
You have your shower room and toillete. Terrace is long and lovely.
This are cold hard facts, but the best part is the location - near Barceloneta metro station, near Parc Cittadela, Arc de Triomph. You have numerous little cafe's and bakeries around (grocery shop also). Santa Catarina market is a 5 minute walk, Catedral is 10 minutes, museum Picasso is 3 minutes.
Barceloneta beach is 5 minutes walking distance. Rambla is 15 minutes away (perfect distance as you don't want to be too close).
Our host was Illia's mom, she's super friendly, speaks English and she has helped as with everything.
Definitely will come back!!
