I stayed at Mariolas apartment for 7 nights in January.
If you are wanting to be slap bang in the middle of the old town this is the place. You have an endless amount of bars and restaurants all within a Ten second to One minute walk away. It really is a hive of activity.
Unsurprisingly Friday and Saturday nights are the loudest, but the sound proof doors block out about 90% of the street noise below. Having said this you may be woken in the night by someone having a sing song in the street. It's luck of the draw and not the owners fault if someone fancies themselves as a poor mans Pavarotti.
The apartment is Good. I would say it's 4 hours maintenance away from being excellent. The upstairs bedroom was fine for me. I'm 6foot and managed to always remember the low beam. The bed is comfy, but needs replacing.
The flat has broadband but i would say it's slow. So if you are there to work it's speed may be a concern.
Overall, it served my needs and i enjoyed myself.
Thank you.
