Everything about the place is great for medium-long term stays, good restaurants, clean, comfortable medium firmness bed, good desk/chair for little work or studying, and location is perfect. No loud venues nearby so sleeping is easy.
There’s affordable gyms nearby that do daily (3eur) and monthly (15eur) memberships within a few minutes if the place, bigger ones within 10minute walk.
Has good netted windows so in summer bugs won’t get in when you have window open, which is rare in Istanbul for some reason.
Everything was great, kitchen a bit small but in the area you don’t need to cook at home at all and has stainless steel pans and stuff if you do want to.
