1) Check-in and Check-out were easy. They allowed us to store our luggage in their office for a few hours after check-out.
2) Cleanliness was very good - no problems there.
3) Accuracy was on the money. Unit looked just like the pictures. 1 room with queen bed, large closet and safe. 2 small rooms with single bed each. Each bedroom had air conditioning, and living room had one too. Small bathroom, but big enough. In-unit washer, but we did not use.
4) Location was excellent - close to Gran Via and tons of great restaurants all around! Taxis were easy to find.
5) Communication was very good. They answered all my questions within a reasonable amount of time.
