I stayed in Lolita's basement apartment for one month, and overall the experience was great. The location was super convenient (less than two blocks from the Georgia Avenue Metro station!). The apartment was in great condition, very clean, and with very nice appliances. The A/C unit in the bedroom was excellent at keeping everything cool. Lolita was very communicative and responsive to my questions. Also, the apartment was very quiet which made it relaxing at the end of a long day.
There were only two downsides for me. First, the ceilings were low and I had to duck down whenever I entered or exited the kitchen (granted, I am 6'5"). Second, the internet was not fast and I experienced glitches when trying to share my screen on Zoom calls. It did feel a bit misleading to see a screenshot of 800+ mbps internet download speeds in the listing, as I personally almost never got over 40 mbps download speeds.
Overall, I would absolutely recommend Lolita's apartment for those looking for a comfortable and quiet place to land at the end of a long day of sightseeing in beautiful DC.
