The place was clean and in a great location to walk around and see Madrid.
However, communication and accuracy were lacking...
Accuracy:
The address says Calle Mayor, 4 but it is actually Calle Mayor, 1. I went into Calle Mayor 4 and they told me that there were only businesses in that building. I showed them the listing, and everyone was confused. Fortunately, someone else who had experienced this before said that the apartment was actually in Calle Mayor, 1.
The room we got was NOT the room that is in the pictures. The room we got is SIMILAR to the pictures, but the room we got did not have the loft space (which we were hoping to have so the kids could go to sleep without the adults walking around them).
Communication:
Our time was 3pm. We sent a message the day before to see what we needed to do for check in. We did not hear anything back. We sent a message at 2pm. We did not hear anything back. We called the number they listed at 2:30pm and were told that we would get that information at 3pm. Although this isn't ideal, if any of our earlier messages would have been answered with a "we will let you know at 3pm" it would have been very helpful.
Finally, after standing in the crowded streets of Madrid with 3 kids and our luggage we got a message at 3:19pm telling us what floor and room number of the apartment. We started by looking for that floor and apartment at Calle 4 (see above).
Also, at 3:19pm we were asked for our "documents" (of which I had to ask, "which documents"). I was not prepared to have to take a photo of our passports and send it to them...it felt sketchy, so be prepared for that.
There were no instructions in the apartment for WiFi. I had to ask for that and send them a screenshot of the available wireless networks...which was weird.
The Place:
The windows did not close well, which allowed a lot of street noise and heat in from outside. However, the place was still comfortable and in an ideal location to walk around and experience Madrid.
Note:
This place seems like it is owned by an organization. When we were contacted it was by different people. I'm guessing this is an organization that owns several similar apartments and manages renting them out.
