Communications to arrange check-in and any questions in between were smooth and quick. Maria was very helpful and nice.
The apartment is handily located right next to the big indoor market and a very good supermarket - as well as 2 min to one subway station and a short walk (10-15 min depending to which one) to a couple other. As we came for a conference, walking to the Fira Via took 20 min - better than train or taxi.
The place was very clean and comfortable. One bedroom is located before the other. So if all 4 are occupied, you need to cross through one. Beware should you come with somebody picky. We ended up with people staying for different days and thus never had all 4 beds used at the same time.
One room as a queen bed and onsuite bathroom - very nice. The other share a second bathroom.
Balconies were fun and nice to use.
Overall, we'd certainly recommend it.
