Lisbon City Stay Largo do Carmo

I have never left a negative review in all my years traveling, but this NEEDS TO BE TOLD. We (a family of 4) stayed at this apartment for four days at the beginning of August. Already started off wrong when after a long flight we just wanted to shower. Well we showered and the shower drain wasn't working, thus having to spend 1 hour drying up the bathroom floor. They send "Carlos" the next day when we were not there. But all nonsense aside.... this is where it gets interesting. We were communicating with Thomas before our stay, she sent some Asian lady to give us the key and "ask for our CC for 150 euro damage deposit". She picked up the phone and called someone with our CC and it hasn't been returned yet (13 days later). We filed a complaint with hotels.com and they advised no charge like that went through their hotel. AS SOON as I checked out, "Thomas" blocked me on WhatsApp where we were communicating. Will never be back and will absolutely leave reviews of this place on every site possible. It not about the 150 euros, it's about the principle. Rent this place at your own risk. Not to mention Hotels.com should remove this listing.
