We absolutely recommend Carolines place. The appartment has two bedrooms with separate bathrooms which are rented out, so you will most probably meet one more couple there at most. The appartment is spacious, has a kitchen and a balcony with very nice view for drinks or coffee. The whole place was veeery clean, and it had everything we might need. Caroline is so thoughtful there was even a sun umbrella :). We didn't meet personaly, bit she was always available on WhatsApp and gave us plenty of recommendations and support.
Finally, the locations is also great, 5 mins from everything going on in the city.
We fully recommend Carolines place.
