The room was very nice and had everything we needed. Check-in and communication were efficient and everything was explained well. Any issues were addressed as quickly as possible, The only thing to be aware of is the location, and this was a "double-edged sword."
The room was very centrally located in the Gothic Quarter - just a couple of blocks off Las Ramblas - and we were able to easily walk to most of the places we wanted to visit. The flip side to that, as several reviews have mentioned, is that people may congregate on the streets below into the night and this could become loud at times.
Clearly, there was nothing the hosts could do about this, and they do provide earplugs to help if this happens. Overall, a very nice stay.
