Hola a todos!
OK, I must apologize in advance if this one runs on a bit, but I desperately need advice.

I will be in Madrid, traveling alone, for a week starting May 22. I plan on seeing the normal tourist attractions, museums, etc, but will also be partying every night with the locals. For this reason, I have had to eliminate hostels as a viable option for lodging. It is my understanding that it is a general rule that it is not allowed to bring people back to the hostel if they are not listed as guests upon check-in. I have no problem paying for a double with single use, but still think it may be an issue to bring someone back to my room.
SO.......I have narrowed it to the Hotel Europa (have reservations there now), Hotel Arosa, and an apartment in the Sol area. I REALLY wanted to be in the Chueca district, but it is extremely limited for hotels. I could not even locate anything on the internet for the Hotel Monaco. What's up with that??? I hear it is kind of trashy anyway, but I would still like to check it out. These others are somewhat close to Gran Via, which I figure is as close as I am going to get. Any ideas about these or other hotels, not hostels, in Chueca???? I also am trying to stay under 100 euros.

I would grately appreciate any commentary and/or suggestions. I have exhausted many strings on this site and have found a wealth of info - AWESOME site MM!!!

Muchas gracias!
