I stayed at MiM for 7 nights in July in a junior suite. Overall a nice hotel but I don’t think its quite value for money (2.000 EUR for the 7 nights).
Positive things first: Nice decor, very friendly staff, great roof terracce, spacious room and bathroom.
Whats less positive: Breakfast had limited selections, and was a mess if you came after 9.30’ish: Dirty tables, no cutlery/service even after multiple requests to waiters. No refilling of food. I think the buffett area is to small to service even a half full restaurant - people were standing on top of each other. Not a relaxing way to start your mornings when on holiday.
The gym was basically ok, but a bit dark in the basement and the water was not refilled / no cups available.
The minibar in the room was good and cheap, but you pay 1 EUR for coffee. Small amount but when you pay 285 EUR/night I expect it to be included.
There are no balconies in the hotel. I knew this when booking, so no issue for me. And if the roof top is enough for you then dont hesitate to book.
However, despite a nice stay, next time I will go to Sitges I’ll consider a place with more value for money. 285 EUR/night can get you quite far and MiM is not quite there.
