Marta and Gerardo’s place is exactly as described and as the fotos show with the exception of minor maintenance issues (one of the blinds in the living room wasn’t working properly, it wouldn’t close when we tried to close it, also, the kitchen had some disperfections, both of which we got blamed for because I made the mistake of not reporting it in a timely manner). The apartment is very well located in a residential area and there are many restaurants and supermarkets close by. It’s only a few block always from the metro Prosperidad. The apartment fits 7 people (two in each room and one in the living room) so it’s ideal for large families. Although the apartment was clean when we arrive (it smelled like it had been cleaned hours before our arrival) we did encounter some issues on closer inspection: the oven was full of grease and had to be cleaned by us, we had to wash all the plates and cutlery because many had food residue on them, there was a lot of dust on pillows in the living room, the towels smelled like mold and had to be washed before using them.
Over all it is a great apartment, I would highly recommend this place if you are staying in Madrid. Just make sure that you message the host with every little detail that you may find is not up to par to avoid misunderstandings (take pictures upon arrival of everything you find dirty or broken as not to get blamed afterwards).
