This spot is the perfect quick resolve for solo travelers that need a base in central Madrid (although I can see working well for a small group of friends or family too).
It is cozy, practical, and not even a block away from the Sol metro stop. There’s also a main street close by, which is a plus because other apartments in the area are a little harder to get to by car / taxi, and for this one you can be dropped off fairly close to the building. Needless to say given the location, there’s a lot of options as to where to eat and explore during the day and go out at night from bars and live music / dancing, to clubs and rooftops. Almots anywhere you want to go in Madrid while visiting, you’ll very likely be able to walk from here.
Keep in mind that this place has very little to no soundproofing, so not only will you have to be respectful of neighbors, you’ll also hear easily any music or noise from next door / outside - with that said, I didn’t find this to be a problem at all. Just don’t expect to bring people / hangouts at this apartment beyond reasonable hours.
The place is as charming as Epaul is a host, and the use of space is creative, the pictures really don’t do it justice! It also has a nice little terrace space on the roof which is a nice perk! I have to say the host offers great hospitality and I had to book something last minute for my short visit, and he was super accommodating to my schedule despite it not matching his usual check-in and out hours. Last but not least, I forgot a charger in the apartment and he was nice enough to ship it all the way to the USA! Bonus points in my book.
