Carmela's place is absolutely ideal! Right in the thick of things, but surprisingly quiet. You might hear the odd distant siren or reveller, but with the double-glazed door closed, it's hardly even noticeable.
The terrace is a great place to sit and have a nice glass or wine or start the day with a coffee, and really makes the place something special. Top floor, but with lift access, so you are above the hubbub on the street below.
Literally 2 mins walk from Sol metro, and within walking distance of ALL the central tourist attractions, through lovely streets chock full of tapas bars, cafes and other great eateries. If you're heading to Madrid, Carmela's place is the perfect location.
Although I didn't meet Carmela personally, all our needs were met and she made sure to check in regularly via email.
I will make Carmela's place the ONLY place to stay in Madrid for any of my upcoming visits.
