Overall this is a great apartment to stay in Barcelona!
Teresa (Ilià's mother) welcomed us in this beautiful apartment placed in one of the most lively neighborhood of Barcelona, El Born.
The private part for the guests is really big, it includes a living room with two sofas and the bedroom separated by a glass wall with private bathroom. There is also a private balcony right outside the windows of the living room.
The noise outside might get a little annoying during the night, also because of the glass recycle bin just under the balcony. If you keep the windows closed there will be a lot less noise and you can always use the fan on the ceiling to stay cool in the night.
