First, the good: This was our first visit to Spain for our group of 4, and the apartment was located in a great area of Madrid for getting around. There was easy access to public transit options, and plenty of places to eat/drink nearby. We also thought the sun room, outdoor space and private patio were very nice touches!
However, upon arrival, we did notice a couple of issues. For one, there was a hole in the wall of one of the bedrooms. Then, we found that one of the beds was not on a frame; rather, it was laid on the ground. Thankfully, a headboard was still intact, but this was not the bed we saw in the listing.
Also worth nothing: One of the bedrooms does face the street with a window that opens to a balcony. The balcony was lovely for people watching and taking in the sights and sounds, but if you are a light sleeper, it can be pretty loud at night.
All in all, we enjoyed our experience, and found the apartment to be a good value for two couples on their first trip to Spain. A few fixes and a bit more amenities would put this place over the top!
