Alice's place is great if you are looking to spend a few days getting to know Barcelona. I was there recently with my girlfriend and had a great stay. The location is outstanding, truly in the heart of the gothic neighbourhood. Also, the place was in great condition in terms of cleanliness , and we didn't experience any loud noises at night. Moreover, Alice's daughter Lola was very helpful in providing us with tips about public transport and sightseeing.
The only negative experience we had was on the check-out day. We were told we had to check out at 10am, but when the time came no one was there to receive our key. Several calls later and approx. 30 minutes waiting in the living room, Alice told us she did not know we were leaving on that day, even though it is clearly stated in our Airbnb reservation. This did not cause us any issues as we had plenty of time until our flight, and as a matter of fact she was kind enough to let us keep out luggage in the apartment until we headed to the airport, and lent us towels to go to the beach. But if you are on a tighter schedule make sure to remind Alice of your check out the day before to avoid any inconveniences.
