I will say it give me my top 3 main request when I choose a hotel or an apartment location, cleanliness and decoration.
I travelled with my 2 senior parents and the best thing to do was staying in one place that we can have like our little “home” for 2 weeks. The building has elevator and the place was spacious enough for 3 adults. I believe this apartment could also work for 4 adults but will be little tight although if you are out all day, it’s fine.
It has lots of natural light and loved the long big windows and tiny balcony ( you can only stand there)
I will recommend this place and will also stay back again.
Missing Madrid!
