I wouldn't think twice about returning to the Marco Polo mansion. Everything about it was amazing. The way it's tucked away on a small winding side street, the hidden courtyard where Efi serves up the most amazing Greek dinners (we ate dinner there twice, why go out?) and the timeless atmosphere of a place that is centuries old and immaculately decorated. A coffee table book has even been published about this place, available to peruse and buy in the lobby.
My husband and I went here for our honeymoon in September, so heat was never really a problem. Can't speak for how it is in summertime, but this place was built before air conditioning and they make the most of cross-breezes. Like many hotels in Greece, some rooms for two had two twin beds instead of a queen or king, but we stayed in two different rooms where they had queen-sized beds. (We could only afford the cheapest room, but when Spiros learned we were on our honeymoon he upgraded us for as many nights as he had better rooms available.) One night we stayed in a fabulous suite with soaring ceilings, a separate bedroom and sitting area, a private entrance and courtyard. I felt like a princess!
The one downside, privacy was somewhat lacking. The windows are nearly always open. Depending on what side you're on, that's either to a narrow pedestrian street, or to the hotel courtyard. But I didn't care, my husband and I were both so in love with the charm and uniqueness of this place.
Some couples we met were there were regulars. One was returning for their 10-year anniversary! This is the kind of place to cherish and return to again and again.
One last recommendation: visit Rhodes in the early fall or late spring and you will have SUCH a better experience. The streets were uncrowded and there were better deals everywhere. Everyone told us that being there in summer is to be shoulder-to-shoulder with hundreds of other European tourists.
