The stay was fine, not worth the price in my opinion though. The building is under construction as you will see in other reviews, and there are no signs of it being finished soon. The bed was comfortable, there was a large kitchen and plenty of space. The bathroom was the main issue for me as a solo male traveler. There was no shower, it was a bath with no curtain around it and a shower nozzle to rinse off but nothing to hold it, so there was no easy way to bathe unless you want to take a bath (which I did not).
Location is nothing special, Old Town is not worth the extra hassle to stay in. It's cool to see for a day but the shops and restaurants are overpriced compared to the main city center just a 10 minute walk away, where there are also more options for food, museums, architecture, and so on.
Not the worst stay I've had travelling abroad, and some factors are out of managements control, but not a place I'd stay again
