We were looking for a centrally located apt in Barcelona that had great air conditioning and great wifi and included a washer/dryer. This apt fit the bill perfectly. We were near a metro station but we walked to most locations. The A/C worked great and the whole family enjoyed the excellent wifi. There is a grocery store on the same block that is open till 23:00 which was quite convenient. The apt was quiet and we heard no noise at night.
The bedrooms are a little small which is expected in an older European buildings and the front door lock can be a little tricky so have the host show you how to use it.
