We stayed at Maria's property in May and we had a great time. It is situated in a very central location with close proximity to restaurants and tourist attractions. Everything is in walking distance! There is a taxi stand about 20 meters walk from the property and with 2 children it was easy to get to and from the airport to the apartment.
The property was very clean, had air conditioning and a comfortable bed and sofa bed, nice bathroom and kitchen facilities. Maria supplied a baby cot for our 8 month old which was extremely handy.
The wifi was great and Maria had great recommendations for food and anything else we needed.
We had two minor issues which are related to our children who are 8 months old and 2 years old. We were travelling with 2 prams and getting them up and down the stairs to the lift was tricky. The other issue was with the street performers at night who performed till around 11pm, the noise was quite loud to the point that it made it difficult to sleep on the sofabed (if you are a light sleeper) which was close to the window. Earplugs will solve that problem however.
Overall, I would recommend Maria's place as it met all our requirements.
