Newly renovated, clean, comfortable, quiet. The apartment was perfect for my needs. I had a lot of work to finish and just needed to focus in a clean and quiet location for a night. The apartment is in a somewhat residential area, but also close to markets and restaurants along main avenues. Proximity to central Madrid area for me was ~10-15min taxi ride.
The wifi seemed slightly slower than other locations I stayed in Madrid, but it was good enough to complete my work.
