Short time- apartment in the centre of Madrid (Spain) ✈️ p41 ✈️

I've stayed in an apartment recently in Madrid right inside Plaza Mayor. It was only 100 euro per night for the 2 of us (+50€ cleaning fee).. I never like to get my hopes to high but it was an amazing apartment when we actually got there. It's rented through www.madrid-ac.com Their Plaza Mayor apartment. I couldn't figure out why they were so cheap but they apparently are just starting out in Madrid. It was large, clean, tidy and the Plaza atmosphere was gold. Open the bedroom door and your in Plaza Mayor!

Really? Is the 50E cleaning fee for the entire stay? per night?

We rent amazing apartments in Madrid and charge no cleaning fee.
Only 2 nights is 125 per night (with no cleaning fee) but for the whole week we chrge 85 euros per day for a great apartment.

We have started renting these apartments after having stayed in many different apartments around the world. We have tried to improve what we didn't like and copied what we liked at the apartements we have stayed.
