This apartment was perfect. Very centrally located. The metro station is literally 2 minutes away and if you prefer to walk, you can walk to pretty much all attractions in less than 30 minutes (what I would suggest so you can get to know the city). The apartment is located in Chueca, an LGBTQ+ friendly neighborhood with lots to offer, from shops, food, bars, and nightclubs (all within 2-5 minutes walking from the apartment). It is also walking distance to Malasaña, a hip neighborhood known for its nightlife, bars, and restaurants. Don't let the nightclubs scare you away. We didn't encounter any noise problems during stay and we were able to get uninterrupted sleep through the night.
The apartment itself was impeccable and exactly what is shown in the photos. Very clean, very modern, very spacious, and the bed is so comfortable! 100% recommend staying here! No hesitations.
