Great centrally-located spot! Was here for just over a week. Would stay again, or in any of Karina's other properties.
WiFi was spot on - I work remotely and never had a problem. Kitchen is tiny, but comes with the basics, including a mini-fridge and microwave, and most importantly to me: espresso pods (a must!). I was planning to eat out the whole time anyway - there are so many affordable and delicious restaurants and stands nearby! No hand towels but does include paper towels. She included a couple bottles of cold water in the fridge, which is sweet and appreciated! The kitchen was perfect for my needs.

Bed is super comfy, and the little balcony was a peaceful and delightful way to experience the mornings. The apartment is super central but also surprisingly quiet - a nice respite from the busy city - depending on the other guests in the building. Karina is very communicative and friendly and check-in and out was a breeze.
Bathroom is good; comes with a hair dryer, hand soap, body wash, hand towel and body towels, and shampoo and conditioner. Water gets hot fast and the water pressure in the shower is nice.
She offers a mid-stay cleaning if you're staying a week or longer.
Overall this was a great choice! I'd cheerfully recommend it to solo travelers, couples, and digital nomads.
