Good for a short stay. For a longer stay, read on.
The biggest selling point is the amazing location, with quick access to trains, buses, grocery store and restaurants. It is comfortable for 2-3 adults, more than might be cramped. Though the kitchen space is very small, there are enough dishes and utensils to cook meals.
However, if you are staying for longer than a few days: the internet is patchy if more than 3 devices are connected. A few dishwash packets and laundry detergent packets were given, but nowhere near enough for a 14 day stay. We had to buy basics like bathroom cleaning products, kitchen paper, clothes detergent, toilet paper. The washing machine worked well, but the dryer sometimes gave errors.
Summary: for a short stay of 3-5 days where you don’t have to clean, this place is great. For longer than that, expect that you could have minor discomforts and that you will have to buy basic daily use products.
