Firstly, accommodation is nice, has what you need and location is fine and close to centre /5 mins walk to metro station and then to get to city centre is around 6/7 minutes / only a few stops so this is a good spot for location however we personally was let down by this accommodation.
If you are a up and out during the night kind of person and sleep mostly during the day, this is the perfect place for you.
First night we was woken up by host cooking at 2am, not a big deal though as was only up for an hour or so but not what you expect. Next night she has friends round for a gathering and they were drinking, smoking and talking/playing games till 4.30/5am (the last person left around 5AM and the gathering started at around 10.30/11pm when we were just about to go to sleep.) We slept for 2 hours in total the whole night as we had plans so needed to go out regardless of no sleep. It just ruined our trip. The next time was woken up again by talking so only had 5 hours sleep and then we needed to get our next flight of our trip quite early.
We were in Madrid to explore and see the sights everyday as only there for 3 days so planned to wake up at 8am most days and go explore and a lack of sleep and energy ruined that from someone with a total disregard for other people that they have as guests in their home. Just selfish behaviour we believe.
I would NOT recommend anyone to stay here if they have a similar plan for their own trip and plan to see the sights etc.
