Awesome location nice cosy place for 3 it would be cramped for 4 the rooms are small so if you have big luggage then it will be overwhelming.
if you have heavy luggage then there will be a big problem as there is no lift though host helped us in lifting our luggage up and down.
Grocery shops are closed and kitchen is good enough for small preparations but I would not recommend heavy cooking. In the winter months the central heating works well
Wifi speed and coverage was adequate. Airport transfer from hosts is highly recommend as you would have problem in location if the apartment purely from Google picture (which is inaccurate)
Lastly with restaurants dotted across you will not have an issues in eating out. overall great value for money.
