This apartment is in a safe and secure building, and if you would prefer public transport to walking, it is directly opposite a metro station that takes you to the centre in 5 mins for 2 euro 20. The walk to the centre of Lisbon is 20 minutes, 15 if you have long legs! then a further 8 or so to the waterfront. A daily metro pass is about 6 Euro.
If you are a fitness bod, there are two gyms less than 5 minutes walk. Fitness Hut is brilliant, has lots of classes and brilliant kit. 10 Euro to use for the day.
Virgin Active at Holmes Place is a gold star gym, with a pool and spa, cost is 30 Euro per day.
Good kitchen so you can eat meals in if you would prefer, and a cute balcony that gets the sun in the morning.
Local tip - if you like chicken, visit Bonjardim in the centre.
Nuno is a brilliant host, incredibly quick to reply to messages and very accomodating. I will definitely stay here again if I visit Lisbon.
