Hey there!
I stayed at Hostal Adriano with four other friends in November and had a great time. I would highly recommend it!
It is in a convenient and safe location. The only negatives about Adriano would be the outside of the building and the lack of elevator. The exterior is not very inviting and unrenovated and the lobby and stairwells were being renovated when we were there. In fact, our first impression was not very positve, but upon climbing the steps to the top(4th floor)the door opened to a beautifully decorated, clean, safe, fun place.
Our group stayed in four different rooms while we were there and they were all unique and spacious enough. The furnishings were bright, clean and new. The baths were modern and clean. No problems at all with security, noise, or hot water. Some of the rooms have balconies over Calle de la Cruz but because of the top floor location, noise was not an issue.
The hosts were very nice, friendly and helpful. Each of us had keys to our rooms and the front doors of the building and the Hostal. So, it was not a problem coming in late.
Overall, I would highly recommend Hostal Adriano. Nice people, secure building, great rooms and inexpensive prices.
If the lack of elevator is not a problem for you then take the hike!! Its a great find!
HEHEHEHEHEH
Have fun and enjoy Madrid. It was great time!
