The Sun Hotel isn't close to much but I didn't walk around anywhere, I was there only 1 night. While driving I didn't see anything close. It is very clean the staff were helpful, spoke enough English to understand (I think)? 1 very little, 2 others we got by just fine.
The bath was clean The room was small but I only slept so it was fine. District 5 far from the airport 20 - 30 -40 mins to get there depending the time of the day or night. Early morning is the best.
Didn't use the wifi so can't say anything ok so I won't.
