We had a wonderful stay. Marta`s brother Marcel waited for us until we got to the apartment until midnight and explained everything.
With my dad we wanted separate sleeping rooms which was perfect as they are located away from each other. Both beds were very comfortable. WIFI works fine (I had to do some video conferencing for work)- great connection. The neighbor upstairs react when you hit hard with a bowl on the ceiling and put the TV volume down.
Supermarkets are close by and the best Croissants are at Santa Gloria in the same Rambla Poblenou. To the beach it´s a nice 5-10 min walk.
