Located 2 blocks from Puerta del Sol and 1 block from Plaza Santa Ana, it is an extremely well located place, in an area that has a lot of nightlife and tourism.
Next to the apartment there is a market where you can get basic things to solve a meal, or something to drink, and next there is a cell phone store where you can buy a Vodafone SIM card with data from 5 euros.
The host communicates constantly and helped us with whatever we needed.
The place is simple and a bit dated but the location is worth it.
