Fantastic! We will absolutely look to stay here again if/when we make it back to Madrid.
The location is awesome; super close to the metro, surrounded by restaurants but on a quiet street itself, easy walking distance (10 minutes) to most attractions and still reasonable (25 minutes) to the further ones like the museums. The metro makes it easy to get anywhere too if you don’t want to walk. There’s a grocery store (Carrefour Express) a couple of doors down that has anything you need - try the fresh-squeezed orange juice (zumo)!
The unit itself is super clean and comfortable for four people (very comfortable for two). All sleep in one room, but with a cabinet divider. The main bed is on the firm side and I found it very comfortable; my wife would’ve liked it a little softer. The pillows are the best Ive ever had in a rental. Everything you need to eat in if you want to and lots of options around if you want to eat out as well.
Super safe; there is a coded door on the street and then a coded door to the unit that is super heavy (and actually really cool-looking as it hearkens back to the history of the area).
Super quiet too, even though it’s in a lively neighborhood. We stopped most mornings at Muñiz across the street for excellent chocolate con churros before heading out for the day.
We didn’t have a chance to use the open air terrace in the back of the building very much, but it was nice to step in and just relax for a minute when we did.
The fact that there is a washer/dryer was really nice after we’d been traveling for a few days. Note that it is small and the loads need to be pretty small for it to dry properly (and it takes about three hours total to wash and dry each load) but it was a game changer for us.
Nico was great to work with (even on short notice) and Patrik and his team made getting taxis to and from the airport easy - it was so nice to have that lined up even though taxis pass by a block or so away with some frequency.
Bottom line - you can’t go wrong here!
