Overall good for the price, 4 out of 5. However, expect a comfortable hostel, not a hotel.
It is relatively clean, big and quiet (recently renovated, so looks better than pictures on website). Also have clean shared toilet and shower (which I never needed to queue). The staff are also always friendly and could speak English, also helped to keep the luggage after check-out.
The bed amenities was not very good. Blanket is short and pillows are too thin. Also might be hot during summer despite having fan, but opening window may attract insects inside room. There is no room cleaning or towel change or shampoo or sandals.
Location is not the best, but is fine (except a bit scary at night if solo sometimes). 15min walk to Keleti train station which has many things, and 20 min walk to the famous park and heroes square. Also multiple buses are available within 1 min walk.
Unfortunately seems this is the Budapest pattern that prices are a bit high for the offer (compared to nearby countries), not their problem. Despite some shortcomings, overall was good stay and affordable. I can see they are renovating/improving, so hope it will be better soon!
