This place sits on both ends or the spectrum (good and bad) for me so here goes.
The good: modern spacious room, equipped with kitchen, small dining corner and bathroom. Very nice room! Location is in a bohemian part of town, a little off-center from attractions but it is very well connected by public transport so no sweat there. It is actually a train stop away from Taksim or a 20mins walk. Communication with host was easy, they let you have a WhatsApp number so you can reach out for anything. Check in was simple and smooth.
The bad.... There is no lift and the staircase is a small, winding and narrow stairs so if you are moving luggage up and down, it WILL be a big challenge! There is a bad smell coming from the bathroom pipings that needs to be solved. Room smells of mothballs too...
We enjoyed our stay because the space is very nice, but the little irritants do annoy me because I am sensitive to smell.
