We were in Agas Apartment end of September '14. Aga responded immediately and although she could not be there when we arrived, she organized everything very well.
The apartment has everything you need (bed, shower, Wifi, infos about Barcelona, towels) and is located at about 8 minutes walk to LaRambla and the same to the Port.
However, if you are looking for that little table on the balcony to sit and have a drink (as shown in the picture)... it is not there! Whether the little table on the small balcony nor the bottle of wine in the fridge.
The blanket on the bed was not exactly keeping you warm enough at night. In the living room there is a big hole in the wall, which leads to some kind of store room. The hole is covered by a beach mat that was hung over the hole. The street is VERY noisy, which is mentioned (and did not disturb me much). However, it is a bit ridiculous to ask the guests so intensely to be quiet in the staircase, when there is this immense noise on the streets.
To make a long story short: I can recommend this apartment, but I would recommend the host to invest a little bit of "love and care" into the apartment. It would make a huge difference!
