Apartments have a great location near metro and 10 minutes walk from plaza Mayor. We rarely used metro. Great point is it is located directly on street market area which was really interesting.
Jesus is very communicative and pleasant person, he met us near the metro and explained all the area and gave a lot of information.
The space itself is not big, but enough just for young couple to stay, having almost all facilities except teapot.
The only minuses are hot water (not enough to have a shower one by one, just some one :)) and cigarette smell in the bathroom in the evening.
