Maryel's flat is located in perfect location if you're here to explore Valencia! All best places to visit, bus stops just in front, metro and railway stations really close as well. Apartment is located just in the city center but it is not that noisy that you could expect. Restaurants and cafes are just downstairs and if you're willing to cook by yourself, Maryel has everything in a kitchen that you could need.
Despite that in the flat there are 3 animals there's no way that they can annoy you.
Small hint - don't use GPS to find this apartment. Mainly look for the passage and then it is really easy to find it.
All in all - it is really nice and cozy place that I would recommend!
