Lovely large, clean, quiet apartments, easy check-in process, and WC/luggage drop off on site. Very handy. Also lots of basics included (kitchen roll etc) but only sachets of shampoo/gel, so best bringing your own.
Only downside was the distance from most of the tourist sites - although there’s a metro stop nearby, it doesn’t save much time on simply walking, so we faced a solid 45-60 minute walk one-way each day.
