I stayed here for little over three weeks and it was perfect for my stay as a solo traveller! It didn't feel too small to me at all, I am really impressed by how well planned the room is, it has everything you might need, and more. The shower was surprisingly good with great water pressure, the pillow and blanket were of good quality, the internet was fast. I had a little struggle with getting the electric toilet to flush in the beginning but once I got the technique of it it all worked fine! There is a common toilet in the hallway too tho if needed.
The location is very central so it is easy to walk to many places, and if you don't feel like walking it is right next to a Metro stop. There are multiple grocery stores, restaurants, pharmacies and laundry shops in the neighborhood too.
The host did warn about the stairs, and rightfully so, they are a bit challenging. Do not bring big luggages! I did think the stairs was worth it for the view tho, and I did get used to them pretty fast.
To me the biggest problem with staying here was the noise level as I am a light sleeper. As it is a central location and the window is facing the street, there is quite much street noise, as well as neighbors smashing the doors in the middle of the night. Bring ear plugs!
Other than that, I really did enjoy my stay and would come back!
