We've stayed more than a month in this apartment since September till half of November.
Apartment is nice and comfortable. It looks like it was renovated 2/3 years ago. Very clean and generally well equipped. AC works very good. There is a lift in the building. Everything was like in the pictures. Communication with host was very good, quick response and reaction. Very comfortable service with changing sheets and towels every week.
Location is convenient for touristic purposes, close to La Rambla and metro. Prepare that even with double windows it can get quite loud at night.
I would give 5 stars if I haven't found that the price was quite high in comparison to other, similar, offers at this time.
