The location is fantastic - the street is even reasonably quiet despite being in the heart of restaurant-land. And the price pretty cheap - but you get what you pay for. The two bedrooms are tiny, just room for a bed. The third sleeping space is in a loft-like platform but with no door or walls separating it from the living area below. We were five including children and it was just about OK - it would be very cramped with 6, even if most were children !
A lot of stairs to climb, which we knew and which was fine for us but wouldn't be for everyone.
It's very obvious that this is an apartment owned by a company, not a host. Business decisions have been made to increase profit that a real person would not make - there's nothing in the place when you arrive, not even a tea bag or coffee. How are you supposed to have a drink if you arrive late? And who wants to have to buy a bag of sugar and salt for a couple of days' stay? There isn't even a full roll of toilet paper left, so you have to buy that too. Our stay here was fine, the location is so good - but little things like that don't make you want to leave more than 3 stars.
And don't accept their 'offer' of transport from the airport - total rip-off price. We got a large taxi from the airport for 5 people for well under 20 euro.
