Apartment is nice and clean. Pool and gym are available also during covid, but be aware that reservations can only be made through Blueground's Callcenter situated in India. This did not always work flawlessly. On the other hand they helped me a lot when I accidentally managed to lock myself out of the apartment at night, emergency service arrived within 3 hours in the middle of the night. That was a life saver.
As a European I am not used to it: As everywhere in US, walls are made of paper, so expect to hear your neighbor's music, phonecalls, washing machine,... You get it, everything.
The stay was very pleasant besides of that. I can recommend.
