The pictures you see online are 100 percent accurate. Everything was well thought out and very convenient from the washer / dryer, air conditioning, to the USB chargers in most of the power outlets. Location is great to get around Madrid. Seemed most places were a 10 minute walk. Apartment is on a busy street but you cannot hear anything at night. Our local contact even arranged a car to meet us the airport the day we arrived.
The only downside to our trip was a leaky toilet. the day after we arrived we came home to very bad smell and a puddle on the bathroom floor. we contacted the local person who arranged things for us before we arrived. 3 days went by with no further response from him until I finally contacted the person we booked the apartment through. He was able to send someone over but that was only clean the floor and throw the paper towels we were using to stop the dirty toilet water from leaking in to the room. Toilet was still leaking the morning we left which was a total of 1 week. Words can't describe the terrible smell in that bathroom was the first 3 days. it was a little better for 2 days that someone cleaned the bathroom with bleach. my biggest beef with all involved is the lack of communication once we alerted them to the problem.
Other than that,the apparent was great.
