The place is very well located - we didn't even need a transit pass because everything was within walking distance.
The air conditioning works very well.
The apartment itself is well equipped for short stays (note, there is a clothes washer but it is very small. It did not have enough capacity for 4 days of clothes for 2 travelers. Also, there is no dryer and it takes >1day for clothes to dry so plan ahead).
The apartment was clean.
However, out of all the Airbnb's we did on the Iberian peninsula, communication and check-in was the most difficult with this place (note, language was not the issue). The host would not respond to the questions we asked. They changed the pre-agreed time we could drop off our bags without warning on the day of check-in. They refused to share the correct address with us until 10 mins before we were allowed in (the address provided on the AirBnB was for a nearby building). All of this is extremely inconvenient for tourists who do not have cell phone coverage in a city without access to free wifi. We didn't know where we were going or even if we still had a place to stay the day of check-in.
