Me and another 2 friends visited Rhodes for a week long workshop.
Island Boutique is a very nice place to stay in the city of Rhodes! It is close to plenty of dinning options, a beach within 1 minute that is really good for a beach that close to the city, and it's about 20 minutes from the old city where nightlife is mostly happening.
The room itself was like a proper hotel room, very clean, great room service, and it had a nice island-inspired style!
The only two drawbacks, which are however very common in the area: the internet was almost non-existent (but the same was true for others staying at a 4-star more expensive hotel) and the price was a bit high (again, the area is expensive in general, but you could find places with slightly fewer amenities but half the price).
Overall a great choice in the city of Rhodes!
