This is a good backup plan for a couple of days if almost everything else is booked out in Madrid (as was my case), with some good and some not so good aspects. First, the mattress is quite comfortable, but you need good earplugs if you want to get a good night sleep, because the noise level in the street and in the building is very high. The bedroom is so small that there is no way you can fit your luggage in, even if you travel light, which means you have to leave them in the living room. The appliances are quite new and work well, but if you plan to cook, you will have to purchase or bring everything because there is not even salt and pepper. Also, the only information that you will find in the apartment is the wifi code. If you want to find a supermarket, or anything else, you are on your own. Last but not least, even though the concept of self check-in is usually convenient, you need a cell phone with the ability to make local calls to get into the building. This was my third stay in Madrid during the last couple of years and compared to the other experiences, I would not say that this is a very good value.
