We stayed at Mari's place for ten days. A day before arriving, we got all the necessary information from Mari, so access to the room went smoothly.
The room is spotless and tidy. The kitchen had all the essential utilities. Towels (including the one for the beach) were also available. Bad was comfortable too.
The location is fantastic. And being on the 38th floor gave us an excellent opportunity to watch the sunrise every morning.
Also, you can catch so many local buses around the building. We got a 7-day pass for USD 30, and we travelled all over the island. Buses are pretty frequent there, so every day, we went to different beaches.
Around the building, you can find many local restaurants, coffee shops and convenience stores (two 7/11 shops are so close).
Warm recommendation.
