I must admit, it's very rare in Europe when you are booking 2 star hotel, but getting 4 star hotel quality instead:) That's basically summaries my experience with this hotel.
The hotel is Very close to Plaza del sol, making it the most convenient location in Madrid.
Our room was newly renovated with the modern twist, windows were sound proof, so not much noise from noisy street. The rooms were thoroughly cleaned everyday.
I highly recommend this hotel to anyone.
