Great apartment and very spacious with private bathrooms in all bedrooms. Great location as well! (although one of the bedrooms facing inward was noisier at night due to noisy neighbours/tenants)
It's one flight of stairs up without a lift but still manageable even with luggages.
The hot water is pretty limited if multiple people are showering at once. Water turns cold after the third of fourth person showers and you need to wait for the water to heat up again.
Check in was very smooth and Tarek was very responsive. Overall a great place to stay in Madrid 👍🏻
