BE CAREFUL STAY AWAY FROM THIS FLAT, IT IS A SCAM!!!
The flat is advertised as a 5 star and priced accordingly, however, the quality you get is probably inferior to a hostel.
From the start, the lady checking me in hardly spoke any English. The flat overlooks a very busy road so I think it will be very noisy at night. But I didn't get to experience that, I decided to leave 5 minutes after walking through the door. The furniture is degraded and old (think cheap ikea with years of tear). Beds only have frames and linens are non ironed, the floor is coming off, the dining table is all bubbly (as in the top layer of wood is coming off). All the walls are blackened by years of dirt. Window panes are disgustingly dirty, the window frames are old and the wood stain is coming off. Every door is heavily chipped, bedside lamps are old and rusty. I did not stay in the flat because at this price point I found a true 5 star hotel in the ciudad vieja with a very nice rooftop swimming pool.
