Positive
Room was just enough for the both of us, not the biggest of rooms but sufficient. Everything we needed was there, coffee maker, fridge, cups and plates. Location was excellent being only a few minutes walk to the old port. There are also many restaurants and fast food places very close by ("Tasty" was good).
Negative
Water pressure was almost non existent at times. This is due to the many people using the water at the same time according to the host. It is also a 800 year old flat. Many times, the water simply stopped half way during a shower, it was quite frustrating.
The host was initially nice to us when we arrived. However she became rude and defensive when we messaged her about some problems we faced during our stay (such as the air-conditioner that was leaking which she blamed us for not airing the room which we would if she had told us to and the lack of water, when there was water, it was not hot enough even though her instructions was to wait for 2-5 mins. the whole shower time was cold in 2/3 times we were there or the other way round, no cold water only hot water) so that she could improve in the future. She even threatened to leave a negative review for us and asked us 'to be careful next time'. If it was a misunderstanding which I think it was, no apologies whatsoever have been given by them so far. This obviously did not leave a good impression for us at all.
