We greatly enjoyed the apartment. It is well designed, spacious, had all the items you may need (including kitchen, closets, towels, etc). It's quiet and comfortable. It is located in one of the greatest areas of Leon. A few steps away from the main area of Barrio Humedo, another 2mn walk to the Plaza Mayor and 5-7mn from the Cathedral. Perfect location and apartment.
The only cons (not the owners's fault), but for folks to be aware of, is that it's in a pedestrian area. You can't access it by car. It's about a 5mn walk from the closest drivable area. Also, it is on the 2nd floor (which is 3rd floor in Spain as ground floor is floor 0), with no elevator. This would not have been a problem for us, except that my 82 year old dad was with us and walks with a cane, so the fact I could not drop him off by the door and then he had to go up 3 floors, was challenging. The web description covered these items, but I did not realize about the pedestrian streets. There could be a possibility of driving and dropping off in front of the door of the apt., but its a private pedestrian street for residents (they can park there) and you need a special pass to even get in. When I realized there was a possibility of dropping my dad off with the car, I took the risk of driving through these private streets. Up to you to take the risk.
The last con was that you had to pick up the keys in another location. I never had to do that before in VRBO. Inconvenient. Other places bring you the keys.
