I have had wonderful stay in Ello's apartment. Despite issues that causes Airbnb (blocked my account temporary and cancelled my reservation), Ello was supportive in this situation to make sure my vacation time is not disrupted.
Great host, great apartment, front desk reception is very supportive and fullfil any request you may have.
As of August 11th Sauna is not available due to COVID-19. It wasn't priority for me, but if for some of you, make sure you check the most recent information.
Gym is OK to do basic stuff (heavy lifiting like deadlifts, squats and benchpress is not available)
Overall, very positive experience
