I’ll start with the great. Location, location, location! This apartment is perfectly located for both short and long visits. My family and I stayed for 8 days over the New Years holiday and absolutely loved every minute of it. We were 2 blocks away from Puerta del Sol and surrounded by some excellent bars , restaurants, and all sorts of entertainment all within walking distance. The train and bus lines are all close and catching an Uber or Taxi was as easy as walking one block up. We couldn’t have asked for a better spot.
That being said, it does get a little noisy at night. If you’re looking for a quiet spot for reading and relaxing this isn’t the place for you. However if you’ve done your research on the great people of Madrid you will have learned that they love their nightlife so plan accordingly.
Back to the apartment and location. It is next door to an electronics shop and pharmacy one door down and both came in handy as we needed power converters and some medicine. There is also a well supplied convenience store to get water, snacks, etc about 1 block down and a grocery store about 1/4 mile walk away so you can buy some food to cook.
And the last thing I’ll say about the location is that most tour companies have you meet close by so you won’t have to walk far for that either.
So the only cons I will mention are with regards to checking in/communications. I prefer a personal touch when paying for lodging and would have liked the owners to meet us in person upon checking in. Also a direct cell phone line. These are more personal preferences than complaints.
All in all I would highly recommend this apartment and would gladly stay again.
