I'm a digital nomad who stayed for several weeks of November. Wifi was solid the whole stay. Check-in was great, someone from the building helped out tremendously and walked me to my door. The fingerprint scan is cool and overall security is A+. There's a convenient rotunda-type pick up spot for Ubers too. The gym is top notch equipment and usually pretty empty. Also there are yoga classes at 8am M/W/F.
LOCATION
I picked this place for the above but it's ~20 minutes from Roma. Ubers are only $5 but it adds up night after night. Since you're almost there, check out Masaryk Avenue, it's really cool and fancy.
OTHER STUFF
Noise - there's a parking garage directly below as well as a road. Bring earplugs and maybe an eye mask as there are no blackout blinds in either bedroom. Hot water worked the whole stay and the washer/dryer is quality.
CLIMATE
Know that in this building and most of CDM, there's no central heating (caleffación). There's a portable heater but it's not enough. Again November is the only month I stayed but... be prepared to be cold everywhere if you're accustomed to central heat.
