My 2 friends and I just spent a month-long work/vacation at Maria's apartment and thoroughly enjoyed our stay. The apartment is exactly how is looks in the pictures. It is very large so everyone had space to relax without being on top of each other. One friend and I were also working while there and we had more than enough space to do it. The wifi was strong and very reliable. The kitchen was fully equipped with a gas stove/oven, microwave, washing machine, lots of pots and pans, and a table for 4. It also has two windows that give a lovely view over a canal. The living room is very large and opens out onto a balcony. I particularly enjoyed sitting out there watching the gondolas glide by. Both bedrooms are quite large with comfortable beds and lots of windows. The bathrooms were both well equipped with strong showers. The only issue was that the toilet in the second bathroom could be temperamental at times.
The apartment sits at the end of a short laneway in a small, quiet building. It is situated at the edge of the Castello & Cannaregio districts which makes it out of the intense tourist areas, but within easy walking distance to all attractions - it was about 15 minutes to San Marco. One warning - be prepared to climb 50 steps to get to it! But I would say the effort is worth it. I would highly recommend a stay at Maria's apartment to anyone.
