The best customer service!! I stayed here with three others in a two bedroom one bath for two nights. The apartment has a lovely little verandah and an amazing ocean view. It also has a small kitchenette with everything you might need (coffee maker being the most important). Even better than the awesome apartment itself, the owner, George, and the person at the front desk, Ergi (spelling?), are two of the nicest people we have ever met! Before we arrived in Santorini, George arranged for a shuttle to pick us up at the port. It was $10 euros a person and completely worth it because it was chaotic at the port and would have been a nightmare to figure out transport ourselves when we disembarked. Plus we were all hot and dusty and just wanted to get to our accomodation.
As soon as we arrived at Rhapsody Apartments, Ergi helped us carry our bags in and gave us a ton of great information on things to do in Santorini. He is really nice and is at the front desk for any questions you might have. We met George in person the next day and he is equally friendly and accommodating. On the second night we had a surprise additional guest and had to make an alteration. George was really helpful and didn't mind being bothered about it even though it was late. We moved to a hostel in Karterados for our next two nights in Santorini but we were all sad to leave Rhapsody. George even drove us to our new hostel with the Rhapsody shuttle for only $5 euros a person because we were having trouble finding a taxi. He told us to contact him if we had any trouble. I cannot recommend this apartment or these hosts enough. Absolutely wonderful!
Regarding the location - Imerovigli is located between the two main towns, Oia and Fira. It's about a 15 - 20 minute walk to Fira (downhill) and a bus ride away from Oia (uphill). It has a few restaurants nearby and two small markets. If you want to eat around Imerovigli, I recommend the restaurant Anestis Tavern for some yummy and affordable Greek fare. It's about a 6 minute walk from the apartments.
