The location is fabulous, and the apartment itself is spacious, modern, and very clean. Shockingly quiet and peaceful given its central location. Some cool features like a hot tub and color-changing lights if you're in the mood to party.
A stone's throw from the Mercado, and easy walking distance to city center and the lively Chueca shops and restaurants. Overall a positive experience, but there were a few cons worth mentioning:
* The back bedroom smelled overwhelmingly of perfume. Like, make you nauseous, can't sleep overwhelming. One of us slept on the living room couch rather than sleep in that room (notably, the couch was really comfortable). The rest of the apartment also smelled, but it was less overpowering. My unworn clothes (which were in a suitcase in the living room) all needed rewashing to get the stink out when I got home.
* The second bedroom is TINY. Just big enough for a bunk bed and a suitcase and nothing else. That room could use an end-table and lamp, also.
* There weren't enough linens and towels. There were extra pillows and blankets, but no extra pillow cases, and for two guests we had exactly two large towels.
* The kitchen could use some additional supplies - dish towels, more cutlery, a coffee maker and/or tea kettle, etc. It's not quite well stocked enough to live and cook in.
* Not really a con so much as an FYI - the artwork on the walls is all large photographs of female nudes. Lots of (very nice looking) butts and boobs everywhere.
