Martha was an amazing hostess, she would respond to my messages very quickly and always with some good news. When I had issues with internet connection she jumped right onto the issue even though it was already 9 pm! The place is tiny but is very well thought through - you have so much equipment for cooking, shelves to unpack etc. that I dare to say it could fit longer stays. Plus you have a terrace on a side where you can scoot in the evening and chill or socialize if guests from other rooms join (it's your own room within hostel-ish type of premises). The area is super safe, surrounded by cafes, restaurants and grocery shops, two metro stations nearby. Great choice! Highly recommend!
