The place is just outside the center of the city (the touristy parts) in a neighborhood called Zizkov. It was very easy either to walk to the city center (about 20 mins) or take an Uber (usually 5-10 mins).
There were five of us and there was more than enough space. The part of the neighborhood was pretty quiet so that was nice too, very quiet while sleeping at night. So a solid place to have relatively easy access to the center of the city while being in a quieter location.
I would definitely stay here again next time I am in Prague, which is an awesome city.
