If you are looking for a hotel with great support and help from the staff this is it! This is the reason why we prefer hotels and not short-term rentals and the staff lived up to expectations. It also is a new and stylish hotel that is a little away from the crazy crowds which we loved as well! A must visit! Kevin

Fantastic hotel; whilst within walking distance of most of the main attraction, bars and restaurants it has quite a tranquil setting. We really loved the pool area and gardens. Breakfast was also a highlight. Also, the staff were lovely and had really funky jumpsuit outfits, which we enjoyed. Room was very comfortable and had a really nice terrace area and access to the pool. I think what they need is a bar and snack/lunch area, which I think they’ll be doing on the rooftop it’s just not fully open yet, but when it is that will be the icing on the cake. Would recommend!
