I rented this apartment for a month. Now I need to recover another month from the back pain the mattress caused me. A previous guest mentioned this matter, and when I asked the host, he assured me it had been changed, but it wasn't.
This is an old apartment with little natural light and only lightened with lamps, so if you want to work from there, better go to a co-working place nearby. It is not well maintained nor adequately cleaned, with the bare minimum for a monthly stay. It's ok for 1-week max but not suitable for a month. I had to request some essential items such as extra bedding (initially I was asked to pay for it lol ), which I am grateful was provided, but still, more effort could be made.
The area is good, the metro is nearby, and many good restaurants are nearby.
