Eloisa was very prompt and sent loads of useful information from before hand on how to arrive at her place. Although wasn't even a problem as we used Uber. You can easily find bus routes using Google maps. Location is amazing. 2 big supermarkets (Mercadona and Lidl) are within 1 minute of walking distance (around 100-150 meters I would say). Lots of shops around the place for food, groceries. Public transport is also right downstairs, you can get a bus to anywhere in Madrid. Also a big roundabout is just 5 minutes from the house, which connects all the public transport. Other famous locations like Reina Sofia museum, Atocha train station, Retiro park, Centro, etc. Are all within walking distances. Also a nice movie theater around 20 minutes by walking. So literally by walking an hour around, you can complete any of these locations. I think for a normal traveler walking for 15 minutes isn't an issue, and you get access to everything.
Now about the place, it is a small studio like room with attached kitchen and toilet. Very well maintained, have all the amenities you'd need, including adapters, tour guides, sufficient toilet paper, linen, pillows, towels. There is extra of everything in the room, stored in cupboard or under the bed. The bed is a convertible ikea, doubles as a big couch. Enough for 2. The room isn't big enough, but yet it's enough to enjoy movies, relax and do your things. The room has a modern TV. So if you have HDMI connector, you can connect your laptop and use it as a big screen for your own movies or internet. Everything in the room was clean. All the amenities mentioned in the description are present. Enough cutlery. The kitchen also have basic needs like salt, oil, rice, seasoning materials. Overall I'm very satisfied, and at this price at this location it's really an amazing deal. Would recommend.
