First of all, all the other reviews about Javier are absolutely true. He is a gracious, generous and helpful host while also respecting your privacy. He welcomed us warmly and the apartment was already set up with a bottle of wine, water, milk and Nespresso pods. He also made us dinner reservations at Juan de la Roca, which had amazing food and was jumping. I'm sure we would not have been able to get in without referral from Javier. He also helped us make other dinner reservations and it seems he is a well known and respected gourmet. Javier was very attentive and responsive. He brought over an extra blanket, loaned us a transit card and provided many tips on local things to do. He even reached out on our last night and helped us arrange a taxi to the airport. I could go on, but he is just simply the best super host I have experienced.
The apartment itself is in the perfect location of Madrid,on a quiet street and square just behind the Royal Palace and Opera house. At night the gardens are lit up and the Opera crowd lets out. The streets are easy, clean and safe to walk everywhere. The Metro is a short stroll away. Mercado San Miguel is touristy, but fun and close by, as are many shops and department stores.
The apartment is very stylishly decorated and designed. Lots of comfy couch space and bright tall windows in the living area. The kitchen is well equipped. The shower is very chic with open concept to the bedroom. There are sliding doors for privacy to the toilet and living area. The lighting was a little confusing (don't touch any of the wall switches, just use the remote) Javier was very patient to explain and came over to fix it when we could not figure it out. The bed is super comfortable and was hard to leave it each morning.
Overall, this is one of the grandest one bedroom apartments I have stayed. It really was the royal treatment from beginning to end.
