Communication with Michel was very easy and check in was very simple. Michel was also very nice to allow us to check out late since we had an evening flight. We never met him in person, but he was very responsive over messenger. The apartment is very spacious and felt totally safe, even when coming home late. There are two metro stations on two different lines within about a 15 minute walk. The towels were nice and fluffy (it's the little things) and the bed was comfortable. It is a good value for the money.
Negatives: It was noisy. The street the apartment is on is quiet but it right next to a loud busy street. But worse than that, there is some kind of mechanical/whirling noise that comes from somewhere in the building and happens about every 60 seconds, 24 hours a day. It's definitely annoying. The one saving grace is that there is a white noise machine in the apartment, so that helped us sleep through all that noise. But there's only one, so one of the bedrooms will have to deal with the sounds. Also, the couch is really old and gross. We weren't hanging out at the apartment much so it wasn't a problem, but I didn't want to sit on it. Also, I wouldn't choose this location again. It's a good mile walk to the most happening/appealing parts of Condesa, though there are a few cute cafes and quiet streets just a few blocks away. It just feels like a big, busy area and isn't the quiet, quaint streets I was hoping for.
